xperiment 2: Find the Density of Iron
Â
Lab Results
Â
Record the initial volume of water (mL) and the initial mass of the graduated cylinder with water (g).
 30.00mL of water & initial mass of graduated cylinder with water = 84.00g
Â
Â
Â
For each of the iron measurements, use the data you collected during the experiment to record the quantities in the table below. Remember to pay attention to significant figures and record all masses and volumes with all the decimals provided by the lab.
Volume of water PLUS iron (mL) 30.64mL 31.27mL 31.91mL 32.54mL 33.18mL
Mass of iron in the graduated cylinder (g) 89.000g 94.000g 99.000g 104.000g 109.000g

Data Analysis
Â
For each of the iron measurements, use the data you collected during the experiment to calculate the quantities in the table below. Remember to pay attention to significant figures and record all masses and volumes with all the decimals provided by the lab. Please note that in this experiment the volume is your least precise measurement containing fewer significant figures than the mass. Therefore, the density can only be as precise as the volume.
Â
Volume of iron ONLY (mL) 0.64mL 1.27mL 1.91mL 2.54mL 3.18mL
Density of iron (g/mL) 7.81 Â
Average density of iron (g/mL) Â
Â
Â
Â
Â
To calculate the Density of iron (g/mL) do I subtract the mass of iron in the graduated cylinder from the mass of the cylinder with water (89.000g - 84.00g)?
