First convert ppm to ppb. 100 ppm = 1,00,000 ppb Now use C1V1 = C2V2 1,00,000 ppb × V1(?) = 500ppb × 50ml V1(?) = 500ppb × 50ml ÷ 1,00,000 ppb V1(?) = 0.25ml Therefore you should take 0.25 ml and mix it with 49.75 ml of water 0.25 ml = 250 microlitres
V2 is the volume that you want to prepare how much solution you need to make Example: you need to prepare 100microgram/ml of 100 ml solution V2 is 100ml
Your teaching method is just brilliant
Bcz of u only i learnt to prepare stock n std solution thank you very much ma'am
It's my pleasure
Nice very informative video
Very nice video mam
Well Done
Please, keep it up with your voice.

Miss I want 1mg/mL solution how to make it???
Madam I want to prepare 100 ppm to 500ppb , volume made up to 50 ml ,then how can I calculate ?? Plse let me know
First convert ppm to ppb.
100 ppm = 1,00,000 ppb
Now use C1V1 = C2V2
1,00,000 ppb × V1(?) = 500ppb × 50ml
V1(?) = 500ppb × 50ml ÷ 1,00,000 ppb
V1(?) = 0.25ml
Therefore you should take 0.25 ml and mix it with 49.75 ml of water
0.25 ml = 250 microlitres
Sorry for late reply, as I was busy with my personal work
How can you determine the V2?
V2 is the volume that you want to prepare how much solution you need to make
Example: you need to prepare 100microgram/ml of 100 ml solution
V2 is 100ml
