100 ml of 1M HCL 200 ml of 2M HCL 300ml of 3M HCL are mixed with enough water to get 1M solutions the volume of water to be added is
Answers
Hey mates your answer is here
Answer:The volume of the solution is 14 mL.
Explanation
Number of moles on 1 M HCL solution in 100 mL
Number of moles on 2 M HCL solution in 200 mL
Number of moles on 3 M HCL solution in 300 mL
On mixing all the solution with water to get 1 M solution HCl.
Total number of moles in resulting solution = 0.1 +0.4+ 0.9 = 1.4 moles
Volume of the resulting 1 M HCl solution = V
The volume of the solution is 14 mL.

In the above question the amount of water added is 800ml
Given,
100ml of 1M OF HCL
200ml of 2M OF HCL
300ml of 3M OF HCL
Assume,
1M = M1
2M = M2
3M = M3
100ml = V1
200ml = V2
300ml = V3
1M = M
=100+400+900 ml
= 1400ml
Therefore
=(1400-(100+200+300)) ml
= 800ml
