Q6 of 29 Page 73

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

7.3g HCl in 100ml solution

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.
