Hello Dawson. Happy to help.

The density is the relationship between the mass of an object and its volume.

so Density =mass of substance/volume of substance.

You measured the mass and volume of water and want to compare the experimental data to the known theoretical value.

First calculate your experimental density.

Density = mass of water 4.83g/volume of water 5.0mL

Density = 0.97g/mL

I am using 2 significant figures in the answer since 5.0 has 2 significant figures.

To calculate the percent error we use the following equation:

(Experimental-Theoretical)/Theoretical * 100

so you have (0.97-1.00)/1.00 *100

You will repeat the same steps for isopropyl alcohol.

I hope this helps. Please reach out to me if you have any additional questions.

0.815 for density. You don't round it to 0.82?02/06/21

So then it would be 4.32 percent?02/06/21

So isopropyl alcohol would be 4.32 percent?02/06/21
