WebAug 4, 2024 · Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1 mol = 22.4 L is the basis for the conversion factor. Example 10.7. 1: Converting Gas Volume to Moles Many metals react with acids to produce hydrogen gas. A certain reaction produces 86.5 L of hydrogen gas at STP. WebThe volume of a gas may be calculated from its number of moles using: volume of gas = moles × Vm rearranging this: \ [moles~of~gas = \frac {volume} {V_m} \] The volume of …
