Q. 6 A4.1( 33 Votes )

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

7.3g HCl in 100ml solution

Class 9th MHB - Science & Technology 5. Acids, Bases and Salts

Answer :

Given:

Weight in grams= 7.3g

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

Molecular mass of HCl = 1+ 35.4 = 36.4 g/mol

Concentration in g/L = 73g/L

Concentration in mol/L = 2 mol/L

Thus, concentration in g/L is 73g/L and concentration in mol/L is 2mol/L.
