Question

A concentration contains 61.04 mL solution in 49.17 g solvent where in the molar mass of the given solute is 32.35. What is the molar concentration of the solution? *
​

Answer 1

Answer:

Explanation:

molar concentration refers to molarity.

so given mass= 49.17g

molar mass = 32.25

no of moles = given mass/molar mass=49.17/32.25=1.5

now conversion of mililitres into litres= 61.04ml into litres= 0.061L

now molarity= no. of moles of the solute/volume of solution (in L)         ...from here u understand why i convert it into litres

now substitute the values= 1.5/0.061=24.59molar

hope it helps!!!!!!!!!!!!

and if u find it helpful mark me brainliest please
