Question

plz answer this question​

Answer 1

No of molecules = no of moles * Na

So for equating no of molecules jzt moles can b equated

=> if mass of N2 = m

Moles= mass/ Molar mass

So, m/ 28=3.6/18

m = 5.6g

(ii) no of moles = no of molecules / Avagadro no.

=6.022*10^22 /6.022*10^23

=0.1

So moles of Ch4= moles of N2 = m/ Molar mass of N2

0.1=m/28

m=2.8g

Answer 2

1)5.6g

2)2.8g
