V(AsH3) = 224 л = 224 дм3

Решение

n(AsH3) = V(AsH3) / Vm = 224 / 22.4 = 10 моль

m(AsH3) = n(AsH3)M(AsH3) = 10 * (75 + 3 * 1) = 10 * 78 = 780 г

N(AsH3) = n(AsH3) * Na = 10 * 6.02 * 10^23 = 6.02 * 10^24

N(As) = N(AsH3) = 6.02 * 10^24

N(H) = 3N(AsH3) = 1.806 * 10^25

Ответ:

N(AsH3) = 6.02 * 10^24

N(As) = 6.02 * 10^24

N(H) = 1.806 * 10^25

N(HF) = 3 * 10^23

Решение

n(HF) = N(HF) / Na = (3 * 10^23) / (6.02 * 10^23) = 0.5 моль

V(HF) = n(HF) * Vm = 0.5 * 22.4 = 11.2 дм3

m(HF) = n(HF)M(HF) = 0.5 * (1 + 19) = 0.5 * 20 = 10 г

Ответ:

V(HF) = 11.2 дм3

m(HF) = 10 г

m(N2O) = 2.2 г

Решение

n(N2O) = m(N2O) / M(N2O) = 2.2 / (2 * 14 + 16) = 2.2 / 44 = 0.05 моль

V(N2O) = n(N2O) * Vm = 0.05 * 22.4 = 1.12 дм3

N(N2O) = n(N2O) * Na = 0.05 * 6.02 * 10^23 = 3.01 * 10^22

N(N) = 2N(N2O) = 2 * 3.01 * 10^22 = 6.02 * 10^22

N(O) = N(N2O) = 3.01 * 10^22

Ответ:

V(N2O) = 1.12 дм3

N(N2O) = 3.01 * 10^22

N(N) = 6.02 * 10^22

N(O) = 3.01 * 10^22
