Question

Calculate the molarity of a solution 7.3g of HCl in 100ml of solution? Calculat the M

Answer 1

Answer:

7.3 g of HCl in 100 mL has concentration = 2mol L−1.

Answer 2

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.
