If 12.0 g of O2 is required to inflate a balloon to a certain size at 27 °C, what mass of O2 is required to inflate it to the same size (and pressure) at 5.0 °C?

Interpretation Introduction

Interpretation: The mass of O2 required to inflate the balloon under given temperature and pressure should be determined.

Concept introduction:

Two equal volumes of gases with same temperature and pressure conditions tend to have same number of molecules with it.

Molar mass: The molar mass of a substance is determined by dividing the given mass of substance by the amount of the substance.

Explanation

Given,

mass of O2 = 12gGas constant, R = 0.0821 L atm mol-1K-1Temperature, T = 27C  =273.15+27 =300
