What is the molar mass of an unknown gas with a density of 2.50 g/L at 1.00 atm and 25.0 °C?
A 1.80−L vessel contains 4.70 g of a gas at 1.00 atm and 27.0°C. (a) Calculate the density of the gas in g/L. g/L (b) What is the molar mass of the gas?
Homework 3 t Gas Density and Molar Mass 6 of 14 > ReviewI Constants Periodic Table ▼ Part B Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.5-L bulb, then filled it with the gas at 1.30 atm and 24.0 °C and weighed it again. The difference in...
