Question

find number of mole present in 18 g of water?​

Answer 1

Answer:

Water has a molar mass of 18.01528 g/mol≈18 g/mol.

So, in 18 g of water, there will be

18g18g/mol=1 mol

Since water has a chemical formula of H2O, there will be 2 moles of hydrogen in every mole of water.

In one mole of water, there will exist approximately 6.02⋅1023 water molecules.

So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024hydrogen atoms.

Answer 2

Answer:

1 mole

Explanation:

No of Moles = GIVEN MOLECULAR MASS / MOLECULAR Mass

Given molecular mass = 18g

molecular mass of water = (H)(2) + O

= (1)(2) + 16

= 2+16 = 18

No of Moles = 18/18= 1 mole
