Determine the number of molecules in a drop of water which weighs 0.09 g. - Chemistry

Determine the number of molecules in a drop of water which weighs 0.09 g.

Numerical

18 g of water has number of molecules = 6.02 x 10²³

∴ 0.09 g of water will have no. of molecules = `(6.02 xx 10^23)/18 xx 9/100`

= 3.01 x 10²¹molecules
