1 L of a gas at S.T.P.weighs 1.97 g. What is the vapour density of the gas?

Text Solution

AI Generated Solution

To find the vapor density of the gas, we will follow these steps: ### Step 1: Understand the relationship between mass, volume, and molar mass at STP At Standard Temperature and Pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. We are given that 1 liter of the gas weighs 1.97 grams. ### Step 2: Calculate the mass of 1 mole of the gas Since 1 mole of gas occupies 22.4 liters, we can find the mass of 1 mole of the gas using the weight of 1 liter: \[ ...
