Question 1204717
Maybe you have an exercise which says:
To prepare 5 L of dextrose solution, you mix 2000 ml. of 50% dextrose with 3000 ml.
of 10% dextrose; and your question might be, what is the resulting concentration?



{{{100(amountPureDextrose/amountVolume)}}}


Figure out the explanation for this expression on your own:
{{{100((2000*0.5+3000*0.1)/(5000))}}}

So now you have choices to select from; so post those choices there!
