Question

Repede dau corona, corecte va tog nu raspunsuri la misto ​

Answer 1

Răspuns:

miu=16g/mol

V= 2 L

p=3,28atm

T= t+273=400K

pV= niuRT.     niu= m/miu

pV= mRT/miu

3,28x2= mx0,082x400/16----> m=3,2g

niu=m/miu= 3,2/16mo=0,2mol=200mmol

1mol molec...........6,022x10²³molec

0,2mol.................x=  1,2044x1o²³ molec

V,c.n=niuxVm=0,2x22,4 l= 4,48 l
