Write the equation and balance it.
H2SO4 + 2NaHCO3 ==> Na2SO4 + 2CO2 + 2H2O
(I think that's balanced but check it out.)
Convert 85 mL of 2.4 M H2SO4 to mols remembering that M x L = mols.
Convert mols H2SO4 to mols NaHCO3 using the coefficients in the balanced equation.
Then use M NaHCO3 = # mols/L. You know M of NaHCO3 and # mols, the only unknown is L.
