Question

Ce masa de dioxid de sulf se afla intr-o incinta de 10L la 4 atm si 27 grade Celsius? Se dau: Mase atomice: S = 32, O = 16, R= 0,082L*atm/mol * K ​

Answer 1

Răspuns:

103,68 g dioxid de sulf

Explicație:

M SO2 = 64g/mol

T= 27 gr celsius + 273 = 300 K

p*V=n*R*T

n=nr de moli

=> n=p*V/R*T

n= 4*10/0,082*300

n= 1,62 moli

=> mSO2 = n*M = 1,62*64 = 103,68 g dioxid de sulf
