Using the dilution expression (ciVi = cfVf or M1V1 = M2V2) calculate the volumes of H2SO4 and KOH needed, given that the actual concentrations of these reagents available in lab (9.00 M H2SO4 and 1.40 M KOH) are different from the concentrations called for in the original procedure (10.0 M H2SO4 and 2.00 M KOH). Finally, scale the resulting volumes down by the factor calculated in (1) above (the factor was 0.0711). Report your volumes to the nearest ±0.1 mL.

What does the mass of 0.7891 mol of ferric oxide (fe2o3)

What is the molar mass of a gas that has density of 2.054 g/l

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
