Sebanyak 150 gr larutan naoh (mr=40) mempunyai konstentrasi sebesar 5m tentukan massa noah dan massa air

Mis massa NaOH = x gr mk
Massa air = (150-x) gr
m = gram/Mr × 1000/m air
5 = x/40 × 1000/(150-x)
5 = 25x/(150-x)
750 - 5x = 25x
30x = 750
x = 25
Jd massa NaOH = 25 gram dan massa air = 125 gram
