Question

A titration was performed in a lab situation. H2SO4 was titrated with NaOH. The following data was collected:
mL of NaOH used = 43.2 mL
concentration NaOH = 0.15 M
mL H2SO4 = 20.5 mL
Notice that H2SO4 releases 2 H+ per mole.

What is the concentration of H2SO4?
a) 0.036 M
b) 0.16 M
c) 0.63 M
d) 6.3 M
