Question
(A) If you have (8.07x10^-2) grams of C6H8O6 (ascorbic acid or vitamin C), how many moles of ascorbic acid do you have? Write your answer in scientific notation, making sure you use the correct number of significant figures and units.
(B) If you have (7.17x10^-2) grams of C6H8O6 (ascorbic acid or vitamin C), how many moles of DCP? will be needed to convert the ascorbic acid completely to products? Write your answer in scientific notation, making sure you use the correct number of significant figures and units.
(C) If you have 0.0581 grams of ascorbic acid and the volume of DCP solution needed to convert the ascorbic acid completely to product is 21.75 mL, what is the molarity (concentration) of the DCP solution? Make sure you use the correct number of significant figures and units.
Explanation / Answer
m = 8.07*10^-2g of C6H8O6, how many moles of Ascorbic acid you have
MW of C6H8O6 = 176.12 g/gmol
N = mass/MW = 8.07*10^-2g / 176.12 g/gmol = 4.58*10^-4 gmol
n (mol of ascorbic acid) = 4.58*10^-4 gmol
