Question

Aqueous solution of hcl is 38 percent by mass and its density is 1.19g/ml calculate molality and molarity

Answer 1

I've written the formulae alongwith.

Answer 2

Answer:

molality= 10.41m

molarity= 12.38M

Explanation:

molality m= no. of moles of solute / mass of solvent

=38×100/36.5×100

= 10.41m

molarity M= no. of moles/ volume

= 38×1.19/36.5×100

=12.38M
