Answer 1

Explanation:

given :

find the total no of atom present in 180g of water

to find :

present in 180g of water

solution :

• Water has a molar mass of 18.01528 g/mol 18 g/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 6.02.1023-2-1.2-1024 hydrogen atoms.
