500 mL of a 1 in 10,000 solution of adrenaline is required. How many millilitres of a solution containing 0.7 mg/mL of adrenaline would be needed? I was able to come up with 71.42 but it is not the actual answer. The correct answer is 71 ml Could you please tell me where I went wrong with my calculations? solving for C1xV1= C2XV2 0.1 X 500ml= (ml) X 0.7 solving for V2 = 71.42
