Problema Solution

i have a 55 gal drum of glycol at 30% mixture. how much 95% glycol do i need to add to produce a 50% mixture of glycol thank you

Answer provided by our tutors

Let x be the amount of 95% glycol required

(0.3*55 + 0.95x) = 0.5 (55+x)

16.5 + 0.95x = 27.5 + 0.5x

0.45x = 11

x = 24.4 gal
