Відповідь:

Вкажіть формули за якими визначають кількість

речовини:

А) n = N/Na

Б) n = m/M

В) n = V/Vm

Г) D = M1/M2

Вкажіть кількість молекул і атомів у вуглекислому газі

об’ємом 44,8 л: nICO2)=44,8/22,4=2 моль

1молекула - 3 атоми

А) 2*6,02*10²³=12,04·10²³ молекул

Б) 24,08·1023

В)3*12,04·10²³ = 36,12·10²³ атомів

Г) 48,16·1023
