Question

I need help with determining what the average density is for this table. I have made an educated guess, but I am not sure if it is correct. I the volumes of ethanol are 10ml, 20ml, and 30ml. I would like some confirmation and an explanation on how to calculate the average density accurately.

4. In this experiment you took measurements for three volumes of ethanol. Use the data you collected during the experiment to calculate the quantities in the table below. 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 olume 15.786 g 7.893 g 23.679 g Total mass of ethanol (g) Density of ethanol (g/mL) 0.7893 g/mL. 0.7893 g/mL 0.7893 g/mL 0.7893 g/mL Average density of ethanol (g/mL)

Explanation / Answer

Average of any quantity = (summation of all the measurements)/ number of measurements

In the given experiment there are three measurements

So average density = (summation of three measurements)/ 3

=( 0.7893g/mL+0.7893g/mL+0.7893g/mL)/3

= 0.7893g/mL
