Question

HgS вычистить массовую долю​

Answer 1

Ответ:

Mr (HgS) = Ar (Hg) + Ar (S) = 201 + 32 = 233

ω (Hg) = Ar (Hg) ÷ Mr (HgS) ·100% = 201 ÷ 233 · 100% ≈ 86,27%

ω (S) = Ar (S) ÷ Mr (HgS) · 100% = 32 ÷ 233 · 100% ≈ 13,73%

Answer 2

Ответ:

w(S) = Ar(S)/ Mr(HgS) = 32/(32+201) = 32/233) = 0.137
