PLEASE HELP 10.0g of solid sodium carbonate and excess of aqueous acetic acid react to produce sodium acetate, carbon dioxide, and water. When the reaction is complete, 1.98 L of CO2 at STP conditions were produced.

Na2CO3(s) +
2 HC2H3O2(aq) à
2 NaC2H3O2(aq) + CO2(g) + H2O(l)

a) Calculate the maximum amount of carbon dioxide that could had been made under these conditions.

b) Calculate the % yield for the reaction.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
