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).

Thank you in advance! :)

  • Chemistry -

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

    Use PV = nRT to calculate P.
