The mass unit associated with density is usually grams. If the volume (in mL or cm3) is multiplied by the density (g/mL or g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3

    1. You add 9.1 g of iron to 29.30 mL of water and observe that the volume of iron and water together is 30.46 mL . Calculate the density of iron. Express your answer to two significant figures with the appropriate units. 2. Since density depends on the mass and volume of an object, we need both of these values combined in the correct way to solve for density. Keep in mind that we may not be given the mass...
