SUMMARY
The density of an unknown liquid was calculated using the formula D = m / v, where the mass (m) was determined by subtracting the weight of an empty Erlenmeyer flask (48.217 g) from the total weight with the liquid (57.056 g), resulting in 8.839 g. The volume (v) was given as 10.00 mL. The calculated density is 0.8839 g/mL, which should be rounded to 0.884 g/mL based on significant figures, as the volume measurement (10.00 mL) dictates the precision of the final answer.
