Q6 of 29 Page 73

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

4.9g H2SO4 in 200ml solution

Given:

Weight in grams= 4.9g


Volume in liters = 200 mL = 0.2L (1mL= 1/1000L)


Molecular mass of H2SO4 = 2×1+32+4×16 = 98 g/mol




Concentration in g/L = 24.5g/L




Concentration in mol/L = 0.25 mol/L


Thus, concentration in g/L is 24.5g/L and concentration in mol/L is 0.25mol/L.
