Question 626541
To the nearest mL, how much 0.3% ampicillin in solution do you have to add to 40mL of 0.8% ampicillin in solution to have 0.4 mL ampicillin total?
------
Equation:
amp + amp = amp
0.003x + 0.008*40 = 0.4
----
Multiply thru by 1000 to get:
3x + 8*40 = 400
3x = 80
x = 26 2/3 mL (amt of 0.3% amp needed)
