#### Answer:

3330 mL

#### Explanation:

From the chemical equation, we can see that for every mole of

The molar mass (MM) of calcium carbonate is:

The number of moles of calcium carbonate can now be calculated:

So, now we double the answer to get the amount of HCl needed:

Rearranging the concentration formula we can get the volume needed in litres:

Convert to mL:
