0.420 g of an unknown diprotic acid is dissolved in about 60 mL of water in a beaker. The solution is transferred to a 100.00 mL volumetric flask, which is then filled up to the mark. The solution is mixed by inverting multiple times. 25.00 mL of this solution is then transferred to an Erlenmeyer flask for the titration. What mass of the diprotic acid is in the 25.00 mL that is transferred? Provide your answer to the correct number...

1.639 g of an unknown diprotic acis are used to make a 100.00 mL
solutiob. Then 25.00 mL of this solution is trasferred to an
Erlenmeyer flask and is titrated with 0.1008 M NaOH. The titration
endpoint is reaxhed after 0.00432 mol of NaOH is added using the
burette. What is the molar mass of the diprotic acid? Provide your
answer to the correct nuber of significat figures

0.408 g of an unknown triprotic acid are used to make a 100.00 mL solution. Then 25.00 mL of this solution is transferred to an Erlenmeyer flask and is titrated with 0.1125 M NaOH. The initial burette reading is 0.82 mL; when the titration endpoint is reached, the final burette reading is 37.62 mL. How many moles of triprotic acid are neutralized during the titration? Provide your answer in decimal form (e.g. 0.123) to the correct number of significant figures.

An analytical chemist weighs out 0.274 g of an unknown diprotic acid into a 250 ml volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.0600 M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 68.1 ml of NaOH solution. Calculate the molar mass of the unknown acid. Round your answer to 3 significant digits. mol X2 ?
