Didn't understand the 5th question solution, madam. there in the question, it is written as 1L but in calculation you are using 100 for calcualtion madam. Please elaborate why ?
Please explain more on this: A 100 sample of hard water is passed through a column of the ion exchange resin H²R the water coming off the column requires 15 .17 of 0.0265 NaOH for the titration . Determine the hardness of water expressed as ppm Ca²+

Dear please i need your help to guid me how can i calculate the required weight from tetradecane to prepare 1000 ppm from tetradecane in cyclohexane as a solvent , the required volume is 100 ml
Thanks a lot Merci beaucoup Can I ask you a favor please. I do some orchids flasking for fun at home and I am told to use 2000ppm of a product. Can you please confirm that I have to use 2mg per liter. 2mg/L. Thanks a lot for your confirmation. Shiam
I have an a small dought mam, Water tank capacity is =10000 liters , And hypo strenth is 12% madam I reqvired concentration =0.2 -0.5 ppm ,how much of of chemical adding to tank madam pleace tell me
Actually ma'am, I have a project on this topic only. Can you help me personally for this ... I would be so thankful of you.. how to make 1ppm solution from 1g of the solute
But that's presuming both substances have the same mo,ar mass, isnnt it? THis calculus won't work if solute and solution have a different molar mass, if I am not wrong.
A city’s water supply is fluoridated by adding NaF. The desired concentration of F- is 1.6 ppm. How many mg of NaF should be added per gallon of treated water if the water supply already is 0.2 ppm in F-?
+Lavanya Lavanya As explained with example in video...Take 0.001739 g NaOH and dissolve in 100ml distilled water..Practically , to prepare any ppm solution , we increase the volume of solvent as weighing of solute becomes easy...So here even 0.01739 g can be taken and dissolved in 1000mL distilled water to get 10 ppm Na solution.
Could you please explain me how to prepare 100 mL of 2 ppm FeSO4.nH2O solution. The molecular weight of FeSO4.nH2O is given on the level of 399.88 g/mol. Thank you.
in Example 2 the value cums around 19.99 x 10-6 so is it 19.99 x 10-6 ppm or 19.99 ppm, because in 1st example the value cums only 5 that's why 5 ppm. pls explain?
+Vishwanath Zunjar +Vishwanath Zunjar On doing calculation, the answer for e.g 1 is 5ppm and for 2nd e.g it's 19.99 which is almost equivalent to 20ppm. Its not 19.99 x 10-6. Hope this helps.
8,5*10-5parts not grams !!! You assumed that it is the same that is erroneous! You should convert to grams by using the atomic mass unit ! To find the molar mass!!
Ma'am.. I have to mix carbon=1 gm And dichloromethane methane in different concentrations (which is in liquid form in bottle)=50 mg/L, ,40mg/L, 30mg/L Please tell me how to make these solutions with these different concentrations.

Your 3 example is wrong because that's present in you 4.5g but that is wrong 45mg is an correct answer
Complicated
Kch BHI samaj mein nhi Aya🥺
Madam you so complicated the solution
your calculations are wrong
final Solution mass = mass of solute + mass of solvent= total mass so it is mass of solute/ total mass
So u should have added them together like 0,020g + 400g = 400,020g of solution
No I didn't understand
