WebYou can calculate the standard gas density fairly easily. Just take the mass of one mole of the gas and divide by molar volume. For example, using nitrogen, we would have: 28.014 g mol¯ 1 / 22.414 L mol¯ 1 = 1.250 g/L Remember, nitrogen is diatomic, N 2, not N. For water, we have: 18.015 g mol¯ 1 / 22.414 L mol¯ 1 = 0.8037 g/L WebThe ideal gas law says that PV = nRT. We would multiply by T if we wanted to find something like pressure of volume. However, this problem asks us to solve for the number of moles of gas, or n. To do this, you can solve for n in the equation as Sal did, and get n = PV / …
