What is #[HCl(aq)]# in the following scenario?
#1.12*L# volume of carbon dioxide was collected under standard conditions from the reaction between #HCl(aq)# and EXCESS #"calcium carbonate"#?
We assume conditions of
We always start these sorts of problems with a balanced equation:
From the stoichiometric equation, it is clear that whatever quantity of carbon dioxide gas is collected, this is HALF the molar quantity of acid added.
Now, the molar volume of an ideal gas at
To generate this quantity of gas, there MUST have been TWICE this molar quantity of
