Methods of Expressing Concentration I Pharma Analysis I Hindi

- Formula weight and molecular weight have slightly different definitions, though, for many substances, the two measurements are the same (and we've been told the terms are used interchangeably by many chemists).
PPM
Just as percent means out of a hundred, so parts per million ppm mean out of a million. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).
ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000.
ppm is a dimensionless quantity, a ratio of 2 quantities of the same unit. For example: mg/kg.
One ppm is equal to 1/1000000 of the whole:
1ppm = 1/1000000 = 0.000001 = 1×10-6
One ppm is equal to 0.0001%:
1ppm = 0.0001%

ppb or ppt me thoda samjao
well explained
Nice
Please Tell me How to calculate normality and lab normality
Adsorption experimental videos
Sir dilution set krna samjh me nahi aa rha
Thank you sir
in v/v conc when you add 10 ml solute in 100 ml solvent then the solution will be 110 then how the conc is 10% ?
How can we prepare 2.5M 2.5N and 6.5ppm solution of phosphoric acid???
Nice video sir 👍
Sir i did not understand PPM plz make a video on ppm...
Good... Fab
Details me ppm ka video banaiye sir

Nice sir....
Sir lebelclam se ppm kese count kare plzzz sir....
How we can prepare 2% solution of phosphoric acid??
,cod or bod dilution kese lagate h
PPM ka n aya smjh me... contact kese kru apko

Thank you so much sir
Pl want to know that how prepare nacl 3ppm solution?
Thank you sir😊
Kisi bhi product ka PPM nikal sakte sir
AAS par video banaiye Sir
Jess ki aapka material solid hai to kese banage sir
Sir 1 formality will be 0.03 not 0.3
Sir jo 1000 le rhe ho..ppm ki calculation me... Vo to sirf trick k liye hi hai na... Vrna 100 mg leke 100 ml me hi dissolve krva hai na..?? For 1000 ppm
Iska formula hi ye 1000 se into karna
To fir formula hi aisa hai... To % se count kr lena chahiye... For example... for 1000 ppm... 0.1 % solution bnalo.. fir jitna % hai usme 10,000 into krdo...
(0.1×10,000 =1000 ppm)
Isko reverse bhi apply kr skte hai.. 1000 ppm banana hai ... To divide kr skte hai... 10,000 se...
(1000/10,000) = 0.1% solution
there is much confusions in ppm formula please repeat it sir
Sir eak karl Fisher par eak vedio banaye please
Thankyou sir
QAC solution ka ppm batao
Sir if we have not 200mg or enough amount of chemical then how we calculate ppm according to your formula and tricks ..
1mg/1ml =1000 ppm
Thakyou sir
Great
Ppm ki smjh nhi
200mg samjh me nahi aa Raha h
If we have 1000 ppm stock solution and we have to make 700 ppm solution from that stock solution then how we have to prepare?
take 70 ml 1000 ppm solution and add 30 ml water then it will be 700 ppm
For HPLC Dilution
Sir ppm ka smj ni aaya
