The solution for this problem would be:
H + ions from pH = 4.0 x 10^-4 moles.
But H2SO4 gives off 2 moles of H+ ions / mole.
Moles of H2SO4 = 2.0 x 10^-4
Mass = 2 x 10^-4 moles x 98 = 1.96 x 10^-3 grams
1.96 x 10^-3 grams / 10^3 = 1.96 x 10^-6 Kg.

Answer:
All of that is correct i am confused on what u are asking us to answer
Explanation:
6.02x10^22 is one mole, so we can just say it's 1 mol HCl in 2.0 L of water. Molarity is mol/L, so 1 mol/2 L is 0.5 mol/L or 0.5 M. Make sense?
