Answer 1

Hii friend,

Here is your answer...

(1) For H2O..

18g of h2o =6.022 ×10²³ molecules

1.8 g = x molecules

x= 6.022 ×10²² molecules

Total electrons = 8(oxygen) +2(two hydrogen)

Total e— = 10

Total number of e ={x} ×10

= 6.022 ×10²³ electrons......(1)

(2) For CH ,

14 g of CH =6.022 ×10²³ molecules

1.6 g =x molecules

x =1.6 /14 × 6.022 × 10²³

x =0.1142 ×6.022 ×10²³

x =6.882 ×10²² molecules

No. of e– =7 e

Total no. of e =6.882 ×7×10²²

Total no. of e = 4.8174 ×10²³....(2)

This is the total no. of electrons present in both the molecules.

Hope this helps you a little!!!
