Dear Student,

Let the volume of solution is 1L =1000 cm³
​Density of solution =1.50 g cm^-3​

Mass of solution =  1.50 x 1000=1500g 
Mass of HBr = 48 % of 1500 g
= (48 x 1500) / 100 = 720 gm of HBr
Number of moles of HBr = 720 / 81 = 8.89 moles
Molarity = moles of HBr / V(in litre) = 8.89 / 1 = 8.89 M.
