1.	What is molarity of a solution of HCl whichcontains 49% by weight of solute and whosespecific gravity is 1.411) 15.25 2) 16.753) 18.92 4) 20.08
Answer» Answer: Given, 49% WEIGHT by VOLUME HCl solution Therefore, weight of HCl in 1ml of solution = specific GRAVITY x 49% = 1.41 x 49/100 =.6909 g/ml Weight of HCl in 1000 ml of solution = 0.6909 x 1000 = 690.9 g Molarity = weight of HCl in 1000 ml / mol.weight of HCl = 690.9/36.4 = 18.9 M

Answer:

Given, 49% WEIGHT by VOLUME HCl solution

Therefore, weight of HCl in 1ml of solution = specific GRAVITY x 49%

= 1.41 x 49/100

=.6909 g/ml

Weight of HCl in 1000 ml of solution = 0.6909 x 1000 = 690.9 g

Molarity = weight of HCl in 1000 ml / mol.weight of HCl

= 690.9/36.4

= 18.9 M
