Question

1000 ml of solution is made in water by dissolving 90 gram of monobasic acid (mol. wt = 60 ). the density of solution is 0.99 calculate the molarity and normality of solution.

If you give me correct answer nd whole solution I will mark u as brainliest​

Answer 1

Answer:

Consider 1000 mL of water.

Mass of 1000 mL of water =1000×1=1000g

No. of moles of water =

18

1000

=55.5

Molarity =

Volume in litre

No. of moles of water=

1 ×55.5 =55.5M
