Jacques Charles used this reaction to prepare hydrogen gas for his historic balloon flights: Fe(s) + H2SO4(aq) = FeSO4(aq) + H2(
g) He wants to prepare a small test balloon to check flight conditions before he lifts off in his giant balloon. He has 234 grams of iron and 382 mL of 12 M (mol / L) sulfuric acid available. What is the maximum size his test balloon can be in L? The temperature in Paris is a chilly 18 celsius and the atmospheric pressure if 770 mm Hg. (This is a limiting reactant problem).

Answer:- There are moles.
Solution:- It is a unit conversion problem where we are asked to convert mg of aspartame to moles. Aspartame is and it's molar mass is 294.31 grams per mole.
mg are converted to grams and then the grams are converted to moles as:
= moles of aspartame
So, there would be moles of aspartame in 1.00 mg of it.
