Chemistry Cumulative REVIEW Questions and Answers Graded A+ Determine how to find density. Write out the formula. What is the density of an item with a mass of 40.0 grams and a volume of 8.0 milliliters? Show your calculations. Density = mass/volume 40.0 g ÷ 8.0 mL = 5.0 g/mL Provide the density of water? Based on this, would the object from the previous question float or sink in water? Provide an explanation. Water has a density of 1 g/mL. Since the object’s density is greater ...
