Question

What is molarity of the resulting solution obtained by mixing 2.5 Litre of 0.5 M urea solution and 500 ml of 2M Urea solution

Answer 1

Answer:

Explanation:

No. Of moles in first solution = 0.5 x 2.5 = 1.25

No. Of moles in the second solution = 2 x 0.5 =1

Total moles = 1.25 + 1 = 2.25

Total volume = 2.5 + 0.5 = 3.0

Molarity = 2.25 ÷ 3 = 0.75 M

Hope it helps you!!!!
