In conducting this experiment, it was paramount to not only establish accuracy and
precision, but maintain it.
This was done using significant figures so as to establish the highest
degree of accuracy of the item(s) measured and to promulgate that accuracy to precision over
multiple measurements of the same item(s).
Having been previously agreed upon, the
measurements of mass were to be divided by the measurements of volume to yield the density of
This was to be understood as D=M/V.
The aforementioned points were all used to
measure, observe, and record the measuring and proper usage of laboratory glassware with the
goal of discovering the most accurate and precise glassware available.
The equipment used in this experiment included a scale, a 25mL graduated cylinder,
50mL beaker, 125mL Erlenmeyer flask, and a 50mL Buret. Also use a clamp to measure the
water accurately in the Erlenmeyer flask. Begin by using one of the particular glassware. Start
with the 25mL graduated cylinder and measure it on the electronic scale without any liquid and
substance inside of it. After pour the distilled water into the glass to the line at 25mL. Afterwards
take the graduated cylinder and weigh it on the scale and then record that information. To make
the correct calculations one must subtract the original mass of the container from the mass of the
container of the water to find the mass of the water. Then find the density by dividing the mass
by the volume. To find the actual correct density one must then measure the temperature of the
water then look up the density of the water at that temperature in the appendix which is in the
back of the lab manual. To find the percent error subtract the actual density by the measured
density, divided by the actual density multiplied by 100 to find your percent error. Repeat these
steps with each other type of glassware. With the Buret measure the water in the Buret but
