It is a trick question. This HCl is very dilute, the H+ contribution from it is 1/10th the contribution from the water (H+=10^-7).
So here, the H+ is 1.1*10^-7.
pH=-log(1.1*10^-7)=6.96...hardly acid, of course.
A bag contains a mixture of copper and lead BBs. The average density of the BBs is 9.60 .Assuming that the copper and lead are pure, determine the relative amounts of each kind of BB.
