A data is collected from sample in a laboratory.

-- mass of flask, g     52.87g

-- mass of flask and sample, g    53.42

-- Concentration of NaOH solution , M   0.101

-- Initial buret reading, mL 0.50

-- Final buret reading, mL 23.78

1.) What is the mass in grams of the sample?

2.) What volume in liters of NaOH solution was used in the titration?

3.) How many moles of NaOH solution were used in the titration?

4.) How many moles of Ascorbic acid were neutralized?

5.) How many grams of acorbic acid is this?

6.) What is the mass percent of ascorbic acid in the sample?
