Use the exact values you enter to make later calculations. Procedure I: Data – Water Week 4 Experiment Density Complete Table 1. Record the mass and volume to one decimal place (e.g., 4.0 or 6.3 or 0.0) and the mass density accurate to two decimal places (e.g., 1.356 would be entered 1.36). Table 1: Water Procedure II: Data – Ethyl Alcohol Complete Table 2. Table 2: Ethyl Alcohol (0.8 g/cm3) Procedure III: Data – Glycerin Complete Table 3. Table 3: Glycerin (1.3 g/cm3) The mass density of an object is 11.8 g/cc, and its volume is determined to be 16.2 cc. What is the mass of the object? The mass density of an object is 22.0 g/cc, and its mass is determined to be 174 g. What is the volume of the object? The mass of an object is 384 g, and its volume is determined to be 75 cc. What is the mass density of the object? The SI units of mass density are kg/m3, but there are several other common units. One of the most commonly used units of mass density is gram per cubic centimeter, or g/cc. This is because pure water has a mass density of 1 g/cc. It turns out that 1 mL of liquid is equal to 1 cc of volume. So it is also possible to express the mass density of water as 1 g/mL. This makes water a useful tool since it is possible to use graduated cylinders to measure volumes. An object with a mass of 62.0 g displaces 362.5 ml of water when it is completely immersed. What is the buoyant force on the mass? (Use g = 9.8 N/kg as necessary.)
