N(SiO₂) = 1моль
M(SiO₂) = 28+32=60г./моль
m(SiO₂) = 60г.
N(SiO₂) = 6·10²³ молекул
V(н.у.)(SiO₂) = m(SiO₂)÷ρ(SiO₂)=60г.÷1.5г./см³=40см³
n(PH₃) =1моль
M(PH₃) = 31+3 =34г./моль
m(PH₃) = 34г
N(PH₃) = 6·10²³ молекул
V(н.у.)(PH₃) = n(PH₃)х Vm = 1мольx 22.4л./моль= 22,4л
n(CO
₂
) = 1моль
M(CO₂) = 12+32 = 44г./моль
m(CO₂) = 44г.
N(CO₂) =
6·10²³ молекул
V(н.у.)(CO₂) =n(CO₂)х Vm = 1мольх22,4л./моль=22,4л.
