Using Density and YOU TRY IT Volume to Find Mass Problem Determine the mass of an object that, when placed in a 25-mL graduated cylinder containing 14 mL of water, causes the level of the water to rise to 19 mL. The object has a density of 3.2 g/mL. 1. Analyze the Problem Known: Unknown: You know the density and the volume of an object and must determine its mass; therefore, you will calculate the answer using the density equation. 2. Solve for the Unknown Write the density equation. = Rearrange the density equation to solve for mass. and Multiply the values and units. The mL units will cancel out. mass = × 3. Evaluate the Answer The two sides of the equation should be density = If you divide 16 g by 5.0 mL, you get Science Notebook • Analyzing Data 20 = Copyright © McGraw-Hill Education.
