How do I prepare 100mL of 10g/L HCl from concentrated HCl(37%HCl, density 1.19g/mL)
Is it 2.28mL of conc HCl dilute to 100mL with water?
Please show the calculation steps.
M 37% HCl is
1.19 g/mL x 1000 mL x 0.37/36.46 = 12.08M
M 10g/L is
10/36.46 = 0.274 M
Then use the dilution formula of
My answers is 2.268 which rounds to 2.28 mL. I suspect the only difference is in what we used for the molar mass HCl
37% HCl is 0.37g/g
to prepare 100mL of 10g/L HCl solution you need 1g of HCl
then the volume of 37% HCl is
1g/(0.37g/g x 1.19g/mL)=2.27mL
suppose you dissolve 10 grams of HCl gas in 250 ml of water initially at 25 C, what till the final temperature of the solution be?
