Question

calculate the number of molecules in 53.Og H2O.​

Answer 1

Answer:

17.7 *10^23 molecules

Explanation:

given mass = 53 gram

molar mass of H20 = 18 gram.

so, we can calculate moles of water

n( moles) = 53 / 18

1 mole have NA molecules ( avgadro number)

so. 53/ 18 moles have = 53/18 * NA molecules

= 53/18 * 6.022 *10^23

= 17.7 * 10^23.
