1. 85.7 grams of platinum = to how many atoms of platinum?​


Solution:

[tex]\text{number of Pt atoms = 85.7 g Pt} × \frac{\text{1 mol Pt}}{\text{195.1 g Pt}} × \frac{\text{6.022 × 10²³ Pt atoms}}{\text{1 mol Pt}}[/tex]

[tex]\boxed{\text{number of Pt atoms = 2.645 × 10²³ atoms}}[/tex]

2. The density of platinum is 23.4 g/cm3 . Calculate the mass of 75.0 cm3 of platinum.


Answer:

Hope you understand my solution. I'm a newbie here!

Explanation:

Density = Mass / Volume

Mass = Density x Volume

Mass = 23.4 g/cm3 x 75.0cm3

Mass = 1755 grams

Answer:

Platinum is a precious metal; soft, silvery-white, and dense with a beautiful lustrous sheen. It is malleable and ductile and has a high melting point.

Platinum does not oxidize in air even at high temperatures and is unaffected by common acids.

It dissolves in aqua regia (mixture of nitric acid and hydrochloric acid in the ratio 1:3) forming chloroplatinic acid (H2PtCl6).

It is also corroded by halogens, cyanides, sulfur, and caustic alkalis.

8. What are the uses of platinum?


ANSWER: Platinum is also used for electrical components, thermocouple elements, corrosion-resistance apparatuses and dentistry.

Platinum is used extensively for jewelry, manufactured into metal gauzes for nitric acid production and as a catalyst to improve the efficiency of fuel cells. In medicine, platinum compounds are important for chemotherapy.

In 2010, 245 tons of platinum were sold. Of the platinum sold, 113 tons were used for vehicle emissions control devices, 76 tons for jewelry and 35.5 tons went to further the advancement other applications, such as investment, electrodes, anticancer drugs, oxygen sensors, spark plugs and turbine engines. Platinum is used as an alloy agent for various metal products, including fine wires, non-corrosive laboratory containers, medicinal instruments, dental prostheses, electrical contacts and thermocouples. Platinum-cobalt is used to make strong permanent magnets. Platinum-based anodes are used in ships, pipelines and steel piers.

According to the Geological Survey, platinum is also important as a catalyst in synthetic organic chemistry. It is also used as a catalyst in the form of gauze for the partial oxidation of ammonia to yield nitric oxide in fertilizers, explosives and nitric acid.

13. what are the significance of Silver, platinum and Zinc?​


Answer:

Silver is a precious metal and, like gold, often symbolizes riches and wealth. Silver is believed to be a mirror to the soul, helping us to see ourselves as others see us. As a gemstone silver represents hope, unconditional love, meditation, mystic visions, tenderness, kindness, sensitivities, and psychic abilities.

Platinum is widely used as a catalyst for chemical reactions. The most important use of platinum is in vehicles, as a catalytic converter, facilitating the complete combustion of unburned hydrocarbon passing through the exhaust. Platinum is used in jewelry, decoration and dental work.

Zinc is found in cells throughout the body. It is needed for the body's defensive (immune) system to properly work. It plays a role in cell division, cell growth, wound healing, and the breakdown of carbohydrates. Zinc is also needed for the senses of smell and taste.

19. Platinum has a density of 22.5 g/cc, what is the mass in pounds (1lbs) of 5.9 cm 3 of platinum?​


Answer:

0.2904 lbs of Platinum

Explanation:

note that cc is cubic centimeter:

Using the density formula,

D=m/V

22.5g/cm^3=mass(m)/5.9cm^3

m=22.5g(5.9) ---- cc cancels out

m=132.75g

convert g to lbs using the following conversion factors

1 kg=1000 g

1 kg = 2.2 lb

m=132.75g (1 kg / 1000g)(2.2lbs/1kg)

m=132.75(2.2)/1000 lbs

m=290.4/1000 lbs

m=0.2904 lbs

30. Platinum solution science 8


What is Platinum?

Platinum with the atomic number 78 and an atomic mass of 195 in the periodic table is an extremely rare element found in the crust of the earth.

The word Platinum is derived from Platina (Spanish word meaning ‘little silver’), because of its grey-white silvery colour. With an availability of 5g/kg in the earth’s crust, it is one of the rarest elements and is highly valuable for the same reason. Although it was discovered relatively later by European scientists, it has been found in Egyptian tombs dating back to 1200 BC.

Uses of Platinum

It is also used in laboratories for electrodes. Optical fibres, wires, and pacemakers also make use of platinum for better efficiency. Certain compounds of platinum are used in chemotherapy for treating cancer. Some watchmakers use platinum in their watches to make it exclusive. Because of its stable physical and chemical properties, platinum metal is a very useful metal. Despite its rarity, its application is quite widespread. Because of its high stability, platinum is used extensively as a catalyst for chemical reactions. The most common application of this is the Catalytic Converter in cars which converts the Carbon monoxide (CO) and other residual pollutants into Carbon dioxide (CO2) and water vapour. The high malleability, ductility, and inertness of the metal make it especially suitable for making jewellery. Around half of the platinum extracted every year goes into making jewellery.
