Answer:0.45L

Explanation:

molarity=0.15M

Mass=5g

No of moles=mass ➗ molecular mass

Molecular mass of KCL=39.0983x1+35.453x1

Molecular mass of KCL=74.5513

No of moles=5 ➗ 74.5513

No of moles=0.067

Volume in liters=No of moles ➗ molarity

Volume in liters=0.067 ➗ 0.15

Volume in liters=0.45L
