Question

please tell the answer of 1 and 2 ​

Answer 1

Answer:

options 1is 50

options 2is 20

Answer 2

1. Normality of HCl solution= 5 N

Volume of the solution = 100 mL= 0.1 L(1 L= 1000 ml)

Number of gram equivalents of HCl =  

0.1

5

=50 gram equivalents per liter

2. we need to get the total mass of the solution.

The total mass of the solution is given by :

Total mass = Mass of the solute + Mass of the solvent

= 18 + 2 = 20

The mass of the solute = 2

The mass percent of the solute will therefore be given by :

2/20 × 100%

We compute this as follows:

1/10 × 100%

This gives us the following percentage as our answer.

= 10%

The mass percent of the solute is thus 10%

HOPE THIS HELPS :D
