Question

calculate the no. of moles and molecules in 22g of acetic acid .formula of acetic acid is CH3COOH

Answer 1

Explanation:

Molecular mass of Acetic acid = 60.05 g/mol

we know that,

1 mole (6.022 × 10²³) = 60.05 g

∴ x mole = 22

By cross multiplication,

∴ x = 6.022 × 10²³ × 22/ 60.05

   = 2.206  × 10²³ number of molecules

Number of moles =  2.206  × 10²³/ 6.022 × 10²³

                             = 0.365 moles
