(1.7) A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 1.71
g/mL, 1.72 g/mL, 1.71 g/mL, 1.70 g/mL.
If the actual value for the density of the sugar solution is 1.50 g/mL, which statement below best describes her results?
O Her results are accurate, but not precise.
O Her results are precise, but not accurate.
O Her results are both precise and accurate
O Her results are neither precise nor accurate.
The liquid substances mercury (density – 13.6 g/cm³), water (density = 1.00
g/cm) and cyclohexane (density = 0.778 g/cm³) do not mix, but stay separate
as distinct layers.
