same steps as the 50mL and 125mL beakers using the same electronic scale. The next step done was to determine how accurate and precise a 10mL graduated cylinder was. Following all those same steps you were to determine the mass of the water in the glassware then calculate the volume, from there you can figure out your experimental density and the percent error. Lastly wewere to determine the mass of sand by weighing out exactly one gram, if you didn’t take the exact mass using the scoopula you could have added or subtracted sand from the weigh boat. Finally clean up, place distilled water down the sink, pour the sand into the correct waste bucket and properly store your glassware.
