1.	At 15°C and 900 mm pressure, 0.4 gram of a certain gas occupied 3280 mL. If the pressure is changed to 1300 mm at constant temperature. What is the density of the gas?
Answer» t 15°C and 900 mm pressure 0.4 gram of gas occupied 3280 mlConsider, if the pressure is changed to 1300 mm at constant temperatureWe KNOW that, PV = nRTThen, Here, temp = 15°C (15+273); pressure = 1300 nm; MOLAR mass = 0.4 g; and R = 8.314Density of the gas = 0.2172 g/L
