Дано:

m(О2) = 80 г

н.у.

Найти:

n(O2) = ?

V(O2) = ?

N(O2) = ?

Решение:

n = m/M, V = Vm × n, N = Na × n

M(O2) = 16 × 2 = 32 г/моль

n(O2) = 80/32 = 2,5 моль

V(O2) = 22,4 × 2,5 = 56 л

N(O2) = 6 × 10²³ × 2,5 = 15 × 10²³ молекул

Ответ: n(O2) = 2,5 моль; V(O2) = 56 л; N(O2) = 15 × 10²³ молекул
