Question 21042: The chemistry lab contains several solutions. Solution A is 80% acid while solution B is only 30% acid. How much of each solution is needed to make a 200L solution that is 62% acid

You can put this solution on YOUR website!
0.8x+0.3(200-x)=0.62(200)
0.8x+60-0.3x=120
0.5x=60
0.5x%2F0.5=60%2F0.5
x=120
200-120 = 80
Hence for 80% there is 120L solution needed and for 30% there is 80L of solution needed
