Question
Calculate the molecular mass of the following:
Potassium Chlorate.
At mass : C = 12, H = 1, O = 16, Cl = 35.5, N = 14, Cu = 63.5, S = 32, Na = 23, K = 39, Pt = 195, Ca = 40, P = 31, Mg = 24]
Solution
Chemical Formula of Potassium Chlorate = KClO3
KClO3 = 39 + 35.5 + 3 × 16
= 74.5 + 48
= 122.5
