Obtaining an empty and dry 50mL beaker its mass was taken and recorded. Once its empty mass
was recorded the beaker was filled with 40mL of water from the 300mL gathered at the start and
massed again. The new mass was recorded as well. The mass of the water was calculated by
subtracting the weight of the beaker empty beaker from the weight of the beaker with water.
Using the mass of the water and the volume of water from the 50mL beaker the density of the
water was calculated. With the temperature of the water that was taken at the beginning the
theoretical density of water at that temperature was found and then using the theoretical density
and the experimental density the percent error of the beaker was found. Once the calculation
were done the water in the 50mL beaker was replaced back into the 600mL beaker. After
calculating the percent error part one of the experiment was redone two more times and using the
three trials the average density and percent error were calculated. The above procedure was
repeated with a 125mL Erlenmeyer flask using three trials.
