Answer 1

Răspuns:

n=nr. moli

Explicație:

a.

VHCl=2moli.22,4L/moli=44,8L

b.

VCH4=5moli. 22,4L/moli=112 L

c.

MNH3=14 +3=17------->17g/moli

nNH3=170g : 17g/moli=10moli

VNH3=10 moli . 22,4L/moli=224L

d.

MCO2=12+2.16=44--->44g/moli

nCO2=4,4g : 44g/moli=0,1 moli

VCO2=0,1moli.22,4L/moli=2,24 L

e.

nO2= 0,32g : 32g/moli=0,01 moli

VO2= 0,01moli.22,4L/moli=0,224 L

f.

nH2= 1g : 2g/moli= 0,5 moli

VH2=0,5moli. 22,4L/moli=11,2 L
