22.4 litres of a gas weighs 70 g at STP....

22.4 litres of a gas weighs 70 g at STP. Calculate the weight of the gas if it occupies a volume of 20 litres at `27^@C` and 700 mm Hg of pressure.

Text Solution

AI Generated Solution

To solve the problem step by step, we will use the Ideal Gas Law and the concept of proportionality between volume and mass at constant temperature and pressure. ### Step 1: Identify the given data - Volume at STP (V1) = 22.4 L - Weight at STP (W1) = 70 g - Volume at the new conditions (V2) = 20 L - Pressure at the new conditions (P1) = 700 mm Hg - Temperature at the new conditions (T1) = 27°C = 300 K (273 + 27) ...
