Convert % to ppm. This is probably faster.
Ammonia Solution
1% = 10000ppm
25% = 250000 (25/100 = 0.25 X 1000000)
C1V1 = C2V2
C1 = 50 ppm (target solution concentration)
V1 = 100 mL (targer solution volume)
C2 = 250000 ppm (stock solution concentration)
V2 = X (stock solution volume required)
V2 = 0.02 mL diluted to 100mL in a volumetric flask
