Calculate the no. of moles of 54g of water(H2O

Answer 1

Hola bud!

First,you need to find the molecular mass of H2O
1*2+16
=18g

1 mole-18g of H2O
x mole- 54g of H2O
(Cross multiply)
x=54/18
x=3
Therefore,3 moles are present in 54g of H2O.


Hope it helps

Answer 2

Firstly find the molecular mass of H2O

It is 2(1)+16=18

Now formula for number of moles is

Moles= given mass/moleculer mass

So moles=54/18

So is 3 moles
