Question

a solution contains 30 gram of glucose 20 gram of salt and 500 ml of water calculate the mass percent of glucose and salt.

Answer 1

since density of water is 1 gram per ml therefore amount of mass contained in 500 ml of water is 500 grams.
amount of mass of glucose is 30 gram and mass of the salt is 20 gram
so mass percentage of the glucose in water is
=30/500*100= 60%
so mass percentage of salt in the water is
= 20/500*100= 40%

Answer 2

Answer:

40%

Explanation:

since density of water is 1 gram per ml therefore amount of mass contained in 500 ml of water is 500 grams.

amount of mass of glucose is 30 gram and mass of the salt is 20 gram

so mass percentage of the glucose in water is

=30/500*100= 60%

so mass percentage of salt in the water is

= 20/500*100= 40%
