Question

Convert into mole1. 18g of water
2.24g of oxygen gas

Answer 1

Hii .....

Here is your answer.......

18g of H2O

In this goven mass = 18g

Molar mass = 1 ×2 + 16×1

= 2+16 =18g

No. of mole = given mass/molar mass

= 18 /18 = 1 mole...

2.24g of O2

Given mass = 2.24

Molar mass = 16 × 2 =32g

Mo. of mole = given mass/molar mass

= 2.24/32 = 0.07 mole

So 18g of water = 1mole amd 2.24g of oxygen gas = 0.07 mole....

HOPE THIS WILL HELP YOU.......
