Question

what weight of HCL is present in 150 ml of 4.52 molal solution​

Answer 1

Answer:

Weight of HCl is 164.98 g

Explanation:

The molal solution means no. of moles

Let n be the no. of moles = 4.52 mol

let w be the weight of HCl

M be the molar mass of the HCl = 1+ 35.5 = 36.5

n = w/M

4.52 = w/ 36.5

w = 4.52 x 36.5

w = 164.98 g of HCl

If we have to find the molarity of the solution then we use the volume which is given the question

Molarity = No. of moles / volume of the solution (in L)
