Question

calculate the formula mass of sodium carbonate ( Na2C03.10H20).​

Answer 1

Answer:

The formula Maas of sodium carbonate is 104.9888g/mol

Answer 2

Explanation:

Atomic mass of sodium =23

Atomic mass of carbon =12

Atomic mass of oxygen =16

Atomic mass of hydrogen molecule=2

Therefore, mass of sodium carbonate=23

$(23 \times 2) + 12 + (16 \times 3) + (2 \times 10) + 16 = \\ = 46 + 12 + 48 + 20 + 16 \\ = 142$
