Question

calculate the number of moles present in 180 gram of water please

Answer 1

Heya!
--------

◾Number of moles ( n ) = Given mass / Atomic Mass


Here , the Given Mass => 180 grams

Also , the molecular mass of water , H2O

= 2 + 16 = 18 grams

↪Hence the number of moles=> 180/18

=> 180/18

=> 10 moles.

Answer 2

HEY Mate......^_^

Here's ur ans. ⬇

_________________________________

No. of moles present in 180 gram of water

Molecular mass of water ( H2O ) = 16+ 2 = 18 g

= 180/18

= 10 moles
