A student drops an object weighting 15.8 g into an open vessel of ethanol, thus that a volume of ethanol spills out equal to the volume of the object. The experimenter at this time finds that the vessel and it contents weigh 10.5 g more than the vessel full of ethanol only. The density of the ethanol is .789g/cm^3. Explain what is the density of the object?
