Q. 6 C4.7( 24 Votes )

Write down the concentration of each of the following solutions in g/L and mol/L.

3g CH3COOH in 100ml solution

Answer :


Weight in g= 3g

Volume in L = 100 mL = 0.1L (1mL= 1/1000L)

Molecular mass of CH3COOH = 12+3×1+12+16+16+1

= 60 g/mol

Concentration in g/L = 30g/L

Concentration in mol/L = 0.5 mol/L

Thus, concentration in g/L is 30g/L and concentration in mol/L is 0.5mol/L.
