Question

Calculate the formula mass of sodium carbonate (Na2CO3.10H2O) ​

Answer 1

Answer:

106u

Explanation:

Na2CO3 = 2Na + 1C + 3O = 2 × 23 + 1 × 12 + 3 × 16 = 46 + 12 + 48 = 106 u.

Answer 2

Answer:

Hey mate! Here's your answer:

Explanation:

Na = 23 u, C = 12 u, O = 16 u, H = 1 u.

Na2CO3 . 10H2O

(23 * 2) + 12 + (16 * 3) + [10 * (2 + 16)]

46 + 12 + 48 + [10 * 18]

106 + 180

286 u.

So the molecular mass of Na2CO3 . 10H2O (Sodium Carbonate / Washing Soda) is 286 u.
