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[tex]Cl_{2}[/tex] = 0.196 Moles
Molarity of the solution = 3.91 M
Volume in litres =?
molarity is calculated by the formula:
molarity = [tex]\frac{number of moles}{volume in litres}[/tex]
putting the values in the above formula and rearranging it for volume:
volume = [tex]\frac{number of moles}{molarity}[/tex]
volume = [tex]\frac{0.196}{3.91}[/tex]
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.
