Question

If the unknown liquid in letter e has a volume of 5.0mL and a mass of 1.95g, what is its density? Make sure to show all work, use significant figures, and include the final unit. Will the sample float or sink in water?

Answer 1

Answer: Density is 0.39g/ml and will float

Step-by-step explanation:

Density is mass/volume : 1.95g/5.0ml = 0.39g/ml

This sample will float on water because a object with a density less than 1g/cm3 will float. 1 cubic centimeter equal 1 ml.
