Final answer:
The volume of 1.000 kg of ethanol is 1267.79 mL.
Step-by-step explanation:
To find the volume of 1.000 kg of ethanol, we can use the density of ethanol as a conversion factor. The given density of ethanol is 0.7890 g/mL. The density relates the mass of a substance to its volume, so we can rearrange the equation to solve for volume.
Multiplying the given mass by the reciprocal of the density will give us the volume:
V = m/d = 1.000 kg / (0.7890 g/mL x 1000 mL/L) = 1267.79 mL.
Therefore, the volume of 1.000 kg of ethanol is 1267.79 mL.
