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

  1. The volume of 40% solution = 4.3L
    The volume of 5% solution = 5.7L

    How to solve algebra word problems?

    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%
    10 liter * 20%= x liter*40% + (10- x) liter*5%
    10l * 20%= x liter * 35% + 10 liter*5%
    x liter *35 = 10l * 20 – 10l *5= 10l*15
    x liter = 10l *15/35= 4.28 L= 4.3L
    The volume of 40% solution= 4.3L
    The volume of 5% solution= 10L- 4.3L= 5.7L
