To find the mass of ONLY the sand: 1.Find the mass of the empty cup. 2.Find the mass of the sand and the cup. 3.Subtract. Mass
167.5 g - 45 g 122.5 g If the mass of the cup is 45 g, what is the mass of only the sand?
Mass to find the mass of ONLY the sand: 1.Place the EMPTY beaker on the balance. 2.Press the “tare” or “zero” button to get the mass to zero. 3.Fill the container with what you want to weigh, and record the mass.
