How much acetic acid should be weigh to make solution if we have 0.2 M Acetic acid of 500 ml​

Answer»

Answer:

We know,

Number of MOLES/ VOLUME(in l) = Molarity

Volume =500ml or 0.5 l.

Number of moles= Molarity× Volume = 0.2× 0.5= 0.1 moles.

Molar mass of CH3COOH= 60g.

Weight of acetic ACID= Molar mass × No: of moles

= 60×0.1= 6g.
