Automobile batteries use 3.0 M H2SO4 as an electrolyte. How much 2.40 M NaOH will be needed to neutralize 165.7 mL of battery acid? H2SO4(aq) + 2NaOH(aq) → 2H2O(l) + Na2SO4(aq) Round off to 2 significant figures. Do not include unit, L. Do not use scientific notation.
33) If 100. mL of water is added to 25 mL of 5.0 M NaCl solution, what is the final concentration? 34) Calculate the volume of 0.123 M AgNO3(aq) needed to form 0.657 g of Ag2SO4(s) according to the chemical equation: 2AgNO3(aq) + H2SO4(aq) -----> Ag2SO4(s) + 2H20(1). 35) Calculate the concentration of a KCl solution prepared by adding 200. mL of water to 100 mL of 12% KCl solution.
When 27.4 mL of 0.500 M H2SO4 is added to 27.4 mL of 1.00 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate ΔH of this reaction. (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for pure water.)

If the molecular weight of a molecule was 450 daltons, how much would be added to 100mL of water to make a 2 M solution? If the molecular weight if a molecule is 400 daltons, how much would be added to 500 mL of water to make a 0.5 solution?
In a constant-pressure calorimeter, 65.0 mL of 0.810 M H2SO4 was added to 65.0 mL of 0.250 M NaOH. The reaction caused the temperature of the solution to rise from 24.29 °C to 25.99 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184 J/g·K, respectively), what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
A 25 mL sample of a 2.0 M solution of MgCl2 is added to a 500 mL volumetric flask. Water is added to the flask until the total volume is 500 mL. What is the concentration of the resulting solution?
