Enter the answer with the correct number of significant figures and units below.  The total acidity in water samples can be determined by neutralization with standard sodium hydroxide solution. What is the total concentration of hydrogen ion, H+, present in a water sample if 100. mL of the sample requires 8.1 mL of 2.1 ✕ 10-3 M NaOH to be neutralized?

HNO3(aq)+Mg(OH)2(s)→HNO3(aq)+Mg(OH)2(s)→   Express your answer as a chemical equation. Identify all of the phases in your answer.

When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. A titration is performed to determine the amount of sulfuric acid, H2SO4, in a 6.5 mL sample taken from car battery. About 50 mL of water is added to the sample, and then it is titrated with 43.37 mL of a standard 0.5824 molar NaOH solution. You balanced this reaction in a previous problem. How many moles of sulfuric acid are present in the original sample? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: ______x10 ____power_____units
