If a 1 liter sample of lake water has a pH = 8.1, [HCO 3 - ] = 3.09 x 10 -3 M, and [CO

If a 1 liter sample of lake water has a pH = 8.1, [HCO3-] = 3.09 x 10-3 M, and [CO3-] = 1.95 x 10-5 M, what is its final alkalinity after the addition of 2.0 mL of 0.5 M H2SO4 ? Assume that alkalinity only comes from hydroxide and carbonates and the addition of 2 mL is negligible in changing the total volume.
