Question

If 100 g of potassium chloride is present in 200 g of solution , calculate the concentration of solution?​

Answer 1

Answer:

mass of KCl = 7.45g

Molecular wt of KCl= 39+35.5=74.5g

Moles of KCl =  

74.5

7.45

​

=0.1

Molarity =  

massofsolvent(inkg)

moles

​

=  

100×10  

−3

 

0.1

​

=1m

Explanation:

Answer 2

Answer:

Correct option is

A

1 m

Mass of KCl = 7.45g

Molecular wt of KCl= 39+35.5=74.5g

Moles of KCl =

74.5

7.45

=0.1

Molarity =

massofsolvent(inkg)

moles

=

100×10

−3

0.1

=1m
