How many molecules of co2 are there in a sample of dry ice (solid co2) with a mass of 10.8 g?

Sagot :

Carbon dioxide may be found in solid form as dry ice.

What is Dry ice ?

Carbon dioxide may be found in solid form as dry ice. CO2 is widely used for temporary cooling since it does not have a liquid state at normal atmospheric pressure and instead sublimates immediately from the solid state to the gas state.

Dry ice is used as a refrigerant, particularly when shipping perishable goods like meats or ice cream, as it sublimes (passes straight into the vapour without melting) around 78.5 °C (109.3 °F).

Dry ice is carbon dioxide in its solid form.

Mass of CO2 = 10.8g

Molar mass of CO2 = 44g/mol

molecules of CO2 = 10.8g * 1 mol/44g= 0.245 mol * 6.022 * 10²³ molecules/1 mol= 1.48 * 10 ²³molecules.

The number of molecules is 1.48 × 10 ²³molecules

Elaborate:

Mass of CO₂ = 10.8 g

Molar mass of CO₂ = 44 g/mol

molecules of CO₂ = 10.8 g × 1 mol/ 44 g= 0.245 mol × 6.022 × 10²³ molecules/1 mol= 1.48 × 10 ²³molecules

What is solid ?

Carbon dioxide may be found in solid form as dry ice. CO₂ is widely used for temporary cooling since it doesn't have a liquid state at normal atmospheric pressure and instead sublimates immediately from the solid state to the gas state.
