Helium volume to weight conversion - Aqua-Calc
WebOne mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L. Example Problem. A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas? Solution. The formula for Avogadro's law is: #V_1/n_1 = V_2/n_2# Web19 sep. 2024 · Moles can be calculated by dividing the mass with the molar mass. Given the mass is 0.02 grams.
