Molar mass of acetone  = 58.08 g/mol


Density of acetone : 784 kg/m^3 = 0.784g/ml

Mass of acetone = density x volume

= 0.784 x 2 = 1.568g


Moles of acetone = 1.568/58.08

= 0.027


Volume of solution = 45/1000 =

0.045 litres



Molarity = Number of moles/Volume in litres



Molarity = 0.027/0.045


             = 0.6M

Hope You Understand  

Thank You
