I was brought a 1 L perchloric acid and it show a little information on the bottle. its said:
perchloric acid 65 %
so, I want to known the concentration of perchloric acid in this bottle please anyone Help me. and let me knwon how to calculate it.
thanks.

it is said, plain and simple, the concentration is 65%.
if u want to calculate it, all you have to do is divide 65 by 100 and there you go......

Its probably 65% by weight. So
1 litre x 1000 ml/litre x SG g/ml = Perchloric Acid g/litre
Clearly 1 kg of your would contain 650 g of HClO4.
How else do you want it expressed?

the density of perchloric acid is 1.67g /cm^3 so a bottle containing 65% is 1.67*10^3*0.65 =1085.5g/L
as the molecular weight is 1+35.5+64 =100.5, the molarity is 10.8M

The guy above me has it. But he didn't mention that you have to assume the volume of the solution is 1 L.
