Given a #20*g# mass of calcium carbonate, how much carbon dioxide will be generated, when it is added to a #100*mL# volume of #"20% w/w"# solution of #HCl(aq)#?
The units of concentration of the hydrochloric acid are unfortunate.....I gets approx. a
We interrogate the reaction......
And thus moles of
And thus the molar concentration of the hydrochloric acid was approx.
And also moles of
There is thus a stoichiometric excess of hydrochloric acid, and calcium carbonate is the limiting reagent. A
Depending on your syllabus, we know that the molar volume at
How much acid is in excess?
