Question

calculate the molecular mass of sodium carbonate (Na2CO3.10H20​

Answer 1

The molecular formula of sodium carbonate is 286

Explanation:

2×23+12+3×16+10((1×2)+16)

46+12+48+180

286

Answer 2

Answer:

Na = 23

C = 12

O = 16

H=1

● Na2 = 46

● CO3 = 12 + (16×3) = 12 + 48 = 60

● 10 H2O = 180 [H2O = (1×2) + 16 = 18]

Therefore

Na2CO3.10H2O = 46 + 60 + 180 = 286 g/mol
