Solution Steps

Step 1: Calculate the Density of the Unknown Liquid

To calculate the density of the unknown liquid, we use the formula: $$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$$ Given that the mass of the unknown liquid is 728 g and the volume is 577 cm^3, the calculated density is 1.262 g/cm^3 after rounding to 3 decimal places.

Step 2: Compare the Calculated Density with Known Densities

We compare the calculated density with the known densities of possible liquids. The calculated density closely matches the density of glycerol, with a difference of 0.001 g/cm^3.

Final Answer:

The unknown liquid is likely glycerol, based on its density.
