A 3.2-L volume of neon gas (Ne) is at a pressure of 3.3 atm and a temperature of 330 K. The atomic mass of neon is 20.2 g/mol, Avogadro's number is 6.0221023 molecules/mol, and the ideal gas constant is = 8.314 J/mol · K = 0.0821 L · atm/mol · K. What is the mass of neon gas?

Question

A 3.2-L volume of neon gas (Ne) is at a pressure of 3.3 atm and a temperature of 330 K. The atomic mass of neon is 20.2 g/mol, Avogadro's number is 6.0221023 molecules/mol, and the ideal gas constant is  = 8.314 J/mol · K = 0.0821 L · atm/mol · K. What is the mass of neon gas?

anonymous · Answer

Let's treat Neon as an ideal gas. Therefore, we can use$$PV = n RT$$Note that $$n = {mass \over molecular~mass} = {m \over M}$$Therefore, $$PV = {m \over M} RT$$Be sure to use the gas constant the appropriate units, which in this case, is 0.0821.
