Therefore, the molar mass of Na2CO3 is 106 g/mole.
How do you find moles of Na2CO3?
- The formula of sodium carbonate is Na2CO3 so its molar mass is:
- molar mass = (2χ22.99 (Na)) + 12.01 (C) + 3χ16.00 (O)) g mol-1 = 105.99 g mol-1.
- The mass of sodium carbonate required is therefore:
- mass = number of moles (in mol) χ molar mass (g mol-1)
- = 0.0250 mol χ 105.99 g mol-1 = 2.65 g.
