n = N/Nа. --> N = nNа. = 0,3 * 6,02 * = 1,806 * 10^{23}
ответ: 1,806 * молекул
5.
Дано:
N(Cu) = 1,2 * атомов
Найти: n(Cu)
n = N/Nа. = (1,2 * )/(6,02 * 10^{23}) = 0,2 моль
ответ: 0,2 моль
Формулы:
n = N/Nа. = m/M = V/Vm., где
n - количество вещества (моль), N - количество молекул/атомов, Nа. - постоянное число Авогадро (6,02 * 10^{23}), m - масса вещества (г), M - молярная масса, V - объём (л), Vm - молярный объём (22,4 л)
