  2. Aug 10, 2022 · In such a conversion, we use the molar mass of a substance as a conversion factor to convert mole units into mass units (or, conversely, mass units into mole units). We also established that 1 mol of Al has a mass of 26.98 g (Example).

  3. Conversions Between Moles and Gas Volume. Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of \(1 \: \text{mol} = 22.4 \: \text{L}\) is the basis for the conversion factor.

  4. To convert from moles to volume of a substance at STP, standard molar volume (22.4 L/mol) is used as a conversion factor.

  5. The relationship between volume, pressure, temperature and quantity of a gas, including definition of gas density. In a perfect or ideal gas the correlations between pressure, volume, temperature and quantity of gas can be expressed by the Ideal Gas Law.

  6. Aug 11, 2022 · We can use the molar volume, 22.4 L/mol, as a conversion factor, but we need to reverse the fraction so that the L units cancel and mol units are introduced. It is a one-step conversion: \[38.7\, \cancel{L}\times \frac{1\, mol}{22.4\cancel{L}}=1.73\, mol\nonumber \]

  7. We can use the molar volume, 22.4 L/mol, as a conversion factor, but we need to reverse the fraction so that the L units cancel and mol units are introduced. It is a one-step conversion: Test Yourself

  8. This makes for a very useful approximation: any gas at STP has a volume of 22.4 L per mole of gas; that is, the molar volume at STP is 22.4 L/mol (Figure 6.3 “Molar Volume”). This molar volume makes a useful conversion factor in stoichiometry problems if the conditions are at STP.
