Question

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L

Answer 1

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of Cd$Cl_{2}$ = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = $\frac{number of moles}{volume in litres}$

putting the values in the above formula and rearranging it for volume:

volume = $\frac{number of moles}{molarity}$

volume = $\frac{0.196}{3.91}$

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.
