vinegar/water = 0ml/35ml

Question

initial mass (g) = 82.420
final mass with AS(g) = 84.925

How do I figure out

initial mass of AS (g)=
mass of CO2 evolved =
moles of CO2(moles)=
Mass of NaHCO3 (g)=

Answer 1

Totally confusing to me. I MIGHT be able to figure it out if I knew what AS was. But it would be better if you wrote the question in standard format.
