Question

calculate the number of moles and molecules of acetic acid present in 22g of it​

Answer 1

The number of moles is 0.367 and the number of molecules of acetic acid is 2.21× 10²³.

Explanation:

Acetic acid has the formulae as CH3COOH.

As we know, the number of moles = Mass/ Molar mass.

As the molar mass of acetic acid is 60g/mol ( by adding up the molar mass of carbon, hydrogen and oxygen as given in the chemical formula).

The given mass of acetic acid = 22g

Hence, the number of moles of acetic acid = 22/60 which is equivalent to 0.367

Also, we know that 1 mole of acetic acid contains = 6.022 × 10²³ molecules

Hence, the number of molecules in 0.367 moles of acetic acid = 6.022 × 10²³ ×0.367

which is equal to 2.21 × 10²³.
