Answer:
Calculate the formula mass of sodium carbonate (Na2CO3.10H2O).
Explanation:
Formula mass of sodium carbonate:
= (2 x atomic mass of Na) + (1 x atomic mass of C) + (3 x atomic mass of O) + 10 [(2 x atomic mass of H) + (1 x atomic mass of O)]
= 2 x 23 +1 x 12 + 3 x 16 + 10 [(2 x 1) + (1 x 16)]
= 46 + 12 + 48 + 180 = 286u
