The density of an object is calculated by dividing its mass by its volume. Similarly, an object's mass can be determined if the density and volume are known. Calculate the mass of an irregularly shaped object having a density of 4.3 grams per mL and a volume of 87.3 mL. *

What is the mass of 0.46 mol of mgcl2
