:
Let x = amt of sodium in 50 kg
then
(50-x) = amt of chlorine in 50 kg
;
A ratio equation:
35.46%2F23 = %2850-x%29%2Fx
cross multiply
35.46x = 23(50-x)
35.46x = 1150 - 23x
35.46x + 23x = 1150
58.46x = 1150
x = 1150%2F58.46
x = 19.67 kg of sodium
;
:
check:
Chlorine: 50 - 19.67 = 30.33
:
23/35.46 = .6486
19.67/30.33 = .6485; close enough
