Question

Determine the mass of carbon atoms in 150g acetic acid ?

Answer 1

Acetic Acid CH3COOH

Molar Mass of Acetic Acid is 60.05 g/mol

no of moles of Acetic acid in 150 gm of Acetic acid = 150 / 60.05 = 2.4979...

therefore

2 carbon atom weighs in 150 gm acetic acid = 2 * molar Mass of 1 carbon atom * no of moles

= 2 * 12.011* 2.4979

= 60.0049 g
