Mass of graduated cylinder (g) 54.000g 54.000g 54.000g Volume of water (mL) 10.0ml 20.0ml 30.0ml Mass of graduated cylinder plus water (g) 64.000g 74.000g 84.000g 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. 2. In this experiment, you took measurements for three volumes of ethanol. 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.

In this experiment, you took measurements for three volumes of water. 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. 2. In this experiment, you took measurements for three volumes of ethanol. 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. Data Analysis 3. In this experiment, you took measurements for three volumes of water. Use the data you collected during the experiment to calculate the quantities in the table below. 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.
