Answer to six signicant gures. An old bottle labeled "Standardized 6 M NaOH" was found at the back of a shelf in the stockroom.

Answer to six significant figures.An old bottle labeled “Standardized 6 MNaOH” was found at the back of a shelf inthe stockroom. Over time, some of the NaOHhad reacted with the glass and the solutionwas no longer 6 M. To determine its purity,5 mL of the solution was diluted to 100 mLand titrated to the stoichiometric point with13.1 mL of 1.83 M HCl(aq). What is themolarity of the sodium hydroxide solution inthe bottle?Answer in units of MAnswer to six significant figures.10.0 ml of a 0.0680 g/L Cr 3+(aq) solution istransferred to a 50.0 ml volumetric flask andenough deionized water is added to bring thetotal volume of solution to the 50.0 ml mark.Then 20.0 ml of the prepared solution is mixedwith 60.0 ml of deionized water. Calculate themolarity of Cr 3+(aq) in the final solution.Answer in units of M
