calculate the number of molecules present in the 36 g water .

Text Solution

Verified by Experts

The molecules weight of `H_(2) O=18`
Thus ,18 Grams of ` H_(2)O`= 1 mole of `H_(2) O`
` 36 "grams of "H_(2) O = 1 " 2 mole of " H_(2) O`
1 mole of `H_(2) O`
`=6.023 xx 10^(23) ` molecules of `H_2O`.
`=1.204 xx 10 ^(24)` molecules of ` H_2 O`.
