25.0-mL sample of concentrated sulfuric acid, H2SO4, is diluted to 1.00 L and a 25.0-mL sample of the dilute acid is further diluted to 100. mL. Then a 10.0-mL sample of the latest solution is titrated with 0.1075 M NaOH. If 20.8 mL of the NaOH solution is required

A student is given 1.52 g of an unknown acid, which can be either oxalic acid, H2C2O4, or citric acid, H3C6H5O7. To determine which acid she has, she titrates the unknown acid with 0.650 M NaOH. The equivalence point is reached when 52.0 mL are added. Answer the following questions to determine the identity of the unknown acid. 1. How many moles of NaOH are consumed? Moles of NaOH = _____ mol 2. How many moles of H+ acid are available to react if the acid is H2C2O4? 0.0403 mol NaOH Moles of H+ from H2C2O4 = ___ mol 3. How many moles of H+ are available to react if the acid is H3C6H5O7? 0.0403 mol NaOH 0.0573 mol H+ from H2C2O4 Moles of H+ from H3C6H5O7 =  ___ mol

A 0.6136 g sample of a monoprotic acid was dissolved in 20 mL of water. The acid solution was titrated to its endpoint with 34.4 mL of 0.297 M NaOH solution. What is the molar mass of the acid? (express your answer correctly rounded to two decimal places) g/mol

A 30.00 ml sample of carbonic acid is titrated to the endpoint with a 0.1000 M potassium hydroxide solution.  The initial buret reading was 13.04 mL; the final reading was 56.61 mL.  What is the molarity of the acid solution?      0.0759                  0.0472              0.0726          0.283               0.0353
