Description : How many total atoms are there in 51.1 g of water ( H 2 O )?
Last Answer : 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 ... So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.
