HOw much of a 0.075M/L HCl solution is needed to make 800ml at a PH of 5.0

This is a dilution process where the stock solution (high concentartion) is used to prepare diluted ones.
The resulting solution has a pH =5 then anti log pH results in [H3O+] = 1.0x10-5 M
Dilution means number of moles of solute is the same before and after dilution
So CxV = C'x V'
0.075 x V = 1.0x10-5 x 800ml
V= 0.10666 = 0.11 ml are needed for this preparation.
