m(Al) = 54 г
Решение
n(Al) = m(Al) / M(Al) = 54 / 27 = 2 моль
2Al + 6HCl = 2AlCl3 + 3H2
n(H2) = 1.5n(Al) = 1.5 * 2 = 3 моль
V(H2) = n(H2) * Vm = 3 / 22.4 = 67.2 дм3
n(AlCl3) = n(Al) = 2 моль
N(AlCl3) = n(AlCl3) * Na = 2 * 6.02 * 10^23 = 1.204 * 10^24
Ответ:
V(H2) = 67.2 дм3
n(AlCl3) = 2 моль
N(AlCl3) = 1.204 * 10^24
