Check your answers to the density practice problems here.
Warm-up Tuesday February 3, 2015:
1. What is the density (in g/cm3) of a regular metal cylinder if it has a mass of 322 grams, a height of 355 mm and a radius of 23.6 mm? (Hint: Use the following formula for volume of a cylinder: V = πr2h )
2. A student does a density determination lab by measuring the volume of an object using the volume displacement method. The initial volume reading of the water in a graduated cylinder is 20.0 ml and the final volume (when the object was placed into the cylinder) is 28.9 ml. If the mass of the object is 104.67 grams, what is the experimental density of the object?
