How do you determine formula of molar mass?

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

How do you calculate the formula unit of sodium carbonate?

The formula unit mass of a substance is the sum of the atomic masses of all the atoms in the formula unit of an ionic compound. Therefore formula unit mass of Na2CO3 = 2Na + 1C + 3O = 2 × 23 + 1 × 12 + 3 × 16 = 46 + 12 + 48 = 106 u.

How do you calculate the formula mass of sodium carbonate decahydrate?

Look up the elemental masses and add them together, i.e. for Na2CO3⋅10H2O . Failing that just google the molecules, and their molecular masses will be quoted somewhere. The formula mass of sodium carbonate decahydrate, Na2CO3⋅10H2O , is 286 u .

How do you calculate moles of sodium carbonate?

1. The formula of sodium carbonate is Na2CO3 so its molar mass is:
2. molar mass = (2χ22.99 (Na)) + 12.01 (C) + 3χ16.00 (O)) g mol-1 = 105.99 g mol-1.
3. The mass of sodium carbonate required is therefore:
4. mass = number of moles (in mol) χ molar mass (g mol-1)
5. = 0.0250 mol χ 105.99 g mol-1 = 2.65 g.
