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 what is the molar concentration of sulfuric acid in the original sample? Present the answer in the following form. Answer: _____ x10 ___power ___units
Prudent practices in laboratories reduce occupational risks that chemists are exposed to. a) Fire is considered one of the biggest hazards in a laboratory and there are four classes of fire.
