Объяснение:
M (CaSiO₃) = 40 + 28 + 16 · 3 = 116 г/моль
w (Ca) = 40/116 · 100% ≈ 34,5%
w (Si) = 28/116 · 100% ≈ 24,1%
w (O) = 48/116 · 100% ≈ 41,4%
=========
M (KHSO₄) = 39 + 1 + 32 + 16 · 4= 136 г/моль
w (K) = 39/136 · 100% ≈ 28,7%
w (H) = 1/136 · 100% ≈ 0,7%
w (S) = 32/136 · 100% ≈ 23,5%
w (O) = 64/136 · 100% ≈ 47,1%
