Answer:
The mass density will be doubled
Explanation:
- Density is given by dividing the mass of a substance by its volume.
- An increase in mass causes an increase in density and vice versa, while a decrease in volume causes an increase in density and volume.
- Therefore, when the volume is halved, then the density will be doubled if the mass is kept constant.
- This has no effect on the number of moles as the mass is constant.

<span>Answer:
It depends on what came after "0.5440 M H...".
If it was a monoprotic acid, like HCl, the calculation would go like this:
(55.25 mL) x (0.5440 M acid) x (1 mol KOH / 1 mol acid) / (0.2450 M KOH) =
122.7 mL KOH
If it was a diprotic acid, like H2SO4, like this:
(55.25 mL) x (0.5440 M acid) x (2 mol KOH / 1 mol acid) / (0.2450 M KOH) =
245.4 mL KOH
If it was a triprotic acid, like H3PO4, like this:
(55.25 mL) x (0.5440 M acid) x (3 mol KOH / 1 mol acid) / (0.2450 M KOH) =
368.0 mL KOH</span>
