Answer / vani
First convert ppm to %.i.e.50ppm/10,000=0.005%
Then apply c1v1=c2v2;
c1=25%;v1=volume to be taken from 25% solution;
c2=0.005%; v2=100ml
v1=c2v2/c1
=0.005x100/25
=0.02ml
=20µL

Answer / greg
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

Answer / qamaruddin
25%AMMONIA MEANS 25g in 100 ml.
above solution 0.25g/ml or 250mg/ml.
250mg of 25% ammonia solution in 100ml=2.5mg/ml
and dilute 2ml(2.5mg/ml sol)in 100ml = 0.05mg/ml.
0.05mg/ml is equal to 50ppm.

Answer / dinesh solanki
25% ammonia means 25*10000 ppm = 25*10000=250000 ppm
Take 1mL from 25% Ammonia solution ---> 100mL (2500ppm)
Again dilute 2mL to 100mL with water (50ppm)
In short 1mL to 100mL with water and from that 2mL to 100mL with water.

Answer / pavan
25%AMMONIA MEANS 25g in 100 ml.
convert in to mg/ml.
25000mg in 100 ml (i.e2500ppm)
take 2ml of 25%ammonia and dilute to 100 ml that is equal
to 50ppm.
