Hey guys. I'm working on a lab and obviously with the COVID19 issues, we haven't been able to have physical class and I struggle a lot in chemistry as is, let alone having to basically learn it on my own now.

I was given a set of data for our last lab and some questions to fill out. I'm honestly just not sure how to figure out how to get the partial pressure. I have attached the data as well as the questions I'm struggling with.

Any help at all would be welcomed and appreciated. Thank you so much in advance!

Excerpt from the lab manual:
"Here, a 50-mL buret is filled with water and placed upside-down in a 600-mL beaker filled with 300 mL of water. The reaction 250-mL side-arm flasks is fitted with rubber tubing which is then fed under the 50-mL buret. As CO2 gas is produced in the side-arm flask, it exits through the rubber tubing and displaces the water in the buret. Then the volume of CO2 produced by the reaction is determined. Because CO2 is collected over water it is not pure but is mixed with vapor from the evaporation of water."
