Question

calculate the 720 moles of H2O

Answer 1

Mole = given mass / molar mass

720x18 = given mass

12960 = given mass

Answer 2

Answer :

{ I think that you want to know about number of atoms in 720 moles H₂O }

We know that,

1 mole H₂O = 6.023 × 10²³ H₂O atom

∴ 720 mole H₂O

= 720 × 6.023 × 10²³ H₂O atom

= 4.46616 × 10²⁶ H₂O atom
