Question

The density of a solution containing 7.3% by mass of hcl is 1.2 gm/ml.calculate the molarity of the solution.

Answer 1

Explanation:

this this is the formula when mass percentage and density is given and the required quantity which is to be calculate is molarity

Answer 2

Answer:

0.0024M

Explanation:

here 7.3% by mass implies 7.3g of HCL in 100g of solution.

Given:- Density=1.2g/ml And mass of solute i.e HCL is 7.3g

so for finding MOLARITY of the given problem 1st we should find no of moles of solute i.e HCL and then find mass of solution i.e solute+solvent and after getting mass of solution u will find volume with the help of density and put the data in formula of MOLARITY
