A chemist needs a 50% of sulfuric acid. She mix 2 liters of 20% of sulfuric acid with a sample of 60% of sulfuric acid. Write a equatoin that models the situation and use it to find how much the 50% of the sulfuric acid she needs to use?

    Ok, she has figured out how to make 50 percent solution, and the above

    Ok, how much 60Percent she needs?

    2liters*.2 + V*.6=(V+2).5

    solve for V
    .4+.6V=.5V+1
    .1V=.6
    V=6 liters

    check my math.
