What is the mass of a gas with a molar mass of 44.01 g/mol at a temperature of 298 K, a pressure of 0.957 atm and a volume of 1.30L?

Answer:

2.24 g

Explanation:

First we use the PV=nRT formula to calculate the number of moles of the gas:

  • 0.957 atm * 1.30 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
  • n = 0.0509 mol

Then we can use the given molar mass to calculate the mass:

  • Molar Mass = Mass / number of moles
  • 44.01 g/mol = Mass / 0.0509 mol
  • Mass = 2.24 g
