i wanna to prepare 2 , 8 , 15 , 25 , 35 , 45 , 55 , 65 wt % of Tungestophosphoric acid supported on graphene by imprregnation method ....
Thanks
If I got your question right, you want to prepare wt% of acid solution. Then, for example for 8%:
- firstly you find the density of the solvent (if it is water, density is 1). Then, you find the weight of the solvent from equation d=m/v [density=mass(in grams)/volume(in mL)]. Then, you calculate the percentage by dividing mass of specimen (Tungestophosphoric acid) to mass of solvent.
If it is not applicable (for ex. if you don't use solvent) please let me know, so that I can be helpful.
Cheers.
The wt% princinple works that way. You have to have a specimen in a sample. You calculate weight for both specimen and sample. Then you divide specimen to sample and multiply by 100% to get the percentage. Or if the percentage is given, you multiply the percentage by sample weight to know how many grams of specimen you are required to use. I'm not familiar with the impregnation method, but from the data that you have provided I can deduce that the given percentage represents the division of acid weight to the grapehe weight. That is, for 8% you should have (8/100)*m [where m is weight of graphene] of acid in grams.
I wish it was useful.
