Question

A student filled the following pieces of equipment up to the 10 mL mark on each with water. The empty mass of each was determined and after filling the mass of each piece with water was also measured. Calculate the mass of water in each piece of equipment and record in the table above. (Show all calculations) Which instrument allowed the student to determine the most accurate measurement of mass for 10 mL of water at room temperature? Explain why you chose this instrument. Does this agree with your assessment with your own data determined in this lab?

Explanation / Answer

MAss of water

1) 10mL cylinder

Mass of water + cylinder - Mass of cylinder = 51.136 - 41.268 = 9.868 grams

2) 100mL cylinder

Mass of water + cylinder - Mass of cylinder = 145.348 - 135.731 = 9.617 grams

3) 25mL flask

Mass of water + flask - Mass of flask = 33.081-24.331 = 8.75 grams

4) 50mL beaker

Mass of water + beaker - Mass of beaker = 38.593 - 30.837 = 7.756

2) Assuming the density of water the temperature on which experiment is conducted = 1 g / mL

so the 10mL of watr= 10 grams

So the most accurate result (near to 10 grams) is from 10mL graduated cylinder. This will give most accurate results

3) the data of experiment not given.
