Question

Convert 36 gm of water to mole

Answer 1

18gm = 1mole
1gm =1/18 mole
36gm = 1/18 × 32
= 2 moles

Answer 2

Hi there !!!

We are asked to convert the given mass of water to moles.

Here given mass = 36 grams

We have to find the molar mass of water

As we all know  chemical formula of water is H₂O.

∴ Molar mass of H₂O = 2 × 1 + 1 × 16
                                   = 18 grams

So its easy to convert to moles as ,


$No: of moles =$ $\frac{Given. mass}{Molar.mass}$
                           
                             = $\frac{36}{18}$
                           
                              = 2 moles
