a scientist needs 10 liters of a 20% acid solution for an expirement but she only has 5% solution and a 40% solution about how many liters of the 5% and then the 40% solutions should the scientist mix to get the solution she needs

Answers

The volume of 40% solution = 4.3L

The volume of 5% solution = 5.7L

If x would be the of volume 40% solution, then the volume of 5% would be:

10 L= 40% solution volume + 5% solution volume

10 L= x + 5% solution volume

5% solution volume= 10l – x

Then the volume calculation would be:

volume of 20% * concentration of 20% = volume of 40% * concentration of 40% + volume of 5% * concentration of 5%

volumeof 40% solution = 4.3Lvolumeof 5% solution = 5.7L## How to solve algebra word problems?
