AI Generated Solution

To solve the problem of finding the vapor density of a gas given its volume and mass at standard temperature and pressure (S.T.P.), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Data:** - Volume of the gas (V) = 11.2 dm³ (which is equivalent to 11.2 liters, since 1 dm³ = 1 liter) - Mass of the gas (m) = 22 g - Standard Temperature and Pressure (S.T.P.) conditions imply that the molar volume (Vm) of a gas is 22.4 L. ...
