Question

what is 12 mole of sodium carbonate​

Answer 1

Answer:

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.
