Final answer:
The volume that 312 g of alcohol would occupy is 342.86 mL.
Step-by-step explanation:
The density of alcohol is 0.91 g/mL. To find the volume that 312 g of alcohol would occupy, you can use the formula density = mass/volume. Rearranging the formula to solve for volume, you get volume = mass/density. Plugging in the values, you have volume = 312 g / 0.91 g/mL = 342.86 mL.
