The pharmacist needs to measure out 17.5 grams of the 50% powder and 17.5 grams of the 90% powder and should end up with 35 grams of the 70% powder thus making for an easy method of calculation for mixing the two powders.

let us say that:

x = mass of 50% powder

y = mass of 90% powder

 

eqtn 1 overall mass balance: x + y = 35

eqtn 2 poweder balance: 0.50 x + 0.90 y = 0.70 * 35 => 0.50 x + 0.90 y = 24.5

 

Combining equations 1 and 2:

0.50 (35 – y) + 0.90 y = 24.5

17.5 – 0.50 y + 0.90 y = 24.5

0.40 y = 7

y = 17.5 grams

 

x = 35 – y = 35 – 17.5 = 17.5 grams

 

<span>So equal amounts of 17.5 grams each are needed.</span>
