Answer:
CaSO₃·2H₂O
Explanation:
Empirically => CaSO₃·nH₂O
%H₂O = n(H₂O)/f.wt. x 100%
23.1% = n(H₂O)100/Ca + S +3O + nH₂O
23.1 = n(18)·100/[40 + 32 + 3(16) + n(18)]
1800n = 23.1[40 + 32 + 3(16) + n(18)]
1800n = 924 + 739.2 + 1108.8 + 415.8n
1800n - 415.8n = 924 + 739.2 + 1108.8
1385n = 2772
n = 2772/1385 = 2
∴ numerical formula => CaSO₃·2H₂O
