Question

what number do you use to convert moles to liters? moles to atoms? moles to grams?

Explanation:

Step1: Moles to Liters (for gases at STP)

At Standard Temperature and Pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. So the conversion factor is 22.4 L/mol. The formula is: Volume (L) = Moles × 22.4 L/mol.

Step2: Moles to Atoms

To convert moles to atoms, we use Avogadro's number, which is \( 6.022\times 10^{23} \) particles (atoms, molecules, etc.) per mole. The formula is: Number of atoms = Moles × \( 6.022\times 10^{23} \) atoms/mol.

Step3: Moles to Grams

To convert moles to grams, we use the molar mass of the substance. The molar mass (in g/mol) is numerically equal to the atomic or molecular weight of the substance. The formula is: Mass (g) = Moles × Molar Mass (g/mol).

Answer:

• Moles to liters (at STP): Use 22.4 L/mol (conversion factor: Volume = Moles × 22.4 L/mol).
• Moles to atoms: Use Avogadro's number (\( 6.022\times 10^{23} \) atoms/mol) (conversion: Atoms = Moles × \( 6.022\times 10^{23} \) atoms/mol).
• Moles to grams: Use molar mass (g/mol) of the substance (conversion: Mass = Moles × Molar Mass).
