Question

Please help me!!!

A sample of gas has a mass of 0.570 g . Its volume is 109 mL at a temperature of 95 ∘C and a pressure of 754 mmHg .Find the molar mass of the gas.

Answer 1

PV = nRT. You know P(must be in atm), V(must be in L), R and T(must be in kelvin). Solve for n = mols. Then n = grams/molar mass. You know n and grams, solve for molar mass.
