Question

7.45 gram kcl is dissolved in 100 gram water calculate the mole fraction of kcl in the solution. class 12 chemistry​

Answer 1

Answer:

the answer is 1 m

Mass of KCl = 7.45g

Molecular wt of KCl= 39+35.5=74.5g

Moles of KCl =74.57.45=0.1

Molarity = massofsolvent(inkg)moles= 100×10−30.1=1m
