Q7. Calculate no. of Molecules in 36 gm water.?​

Answer 1

12321.012 molocules I think

Answer 2

Here is your answer:-

H2O is the formula for water

Molecular mass = 2(H)+1(O)

= 2 × 1 + 1 × 16

= 2 + 16

= 18 gm

1 gm molecule of water = 18 gm of water

18 gm of water contain 6.023 × 10^23 molecules of water

For 36 gm of water contain

36 × 6.023 × 10^23/18

= 2 × 6.023 × 10^23 molecules of water

2 × 6.023 × 10^23 molecules of water.
