I need help starting this problem:

A piece of dry ice (solid carbon dioxide) with a mass of 4.50 g is sealed inside a 2.0 L bottle, and allowed to sublime. At 22.0 degrees Celsius, what is the partial pressure of the CO2 in the bottle? (Assume that all of the CO2 in the sealed bottle came from the dry ice- the amount already present from the air will be negligible).

1. Convert 4.50 g CO2 to moles. moles = grams/molar mass

Use PV = nRT to calculate P.

Dry ice is solid carbon dioxide. Instead of melting, solid carbon dioxide sublimes according to the following equation: CO2(s)--> CO2(g). When dry ice is added to warm water, heat from the water causes the dry ice to sublime more

Dry Ice. At standard atmospheric pressure, the solid form of carbon dioxide called “dry ice” undergoes a phase change not to a liquid but straight to a gas. This process is called sublimation, and like other phase transitions
