Question

If 10 g of starch is dissolved with water to make 2 litre then what will be the concentration.

Answer 1

Answer:

Mass of solute =10g

Mass of solution =Mass of solute+Mass of solvent

=10 g+100 g

=110 g

Mass % =

Mass of solution

Mass of solute×100

=

110

10×100

=9.09=9.1%

I have taken the different value you can solve by arranging the values given in the question

Answer 2

Answer:

mass

Explanation:

Correct option is

B

9.1

Mass of solute =10g

Mass of solution =Mass of solute+Mass of solvent

=10 g+100 g

=110 g

Mass % =

Mass of solution

Mass of solute×100

=

110

10×100

=9.09=9.1%
