please answer the questions by looking at the values provided on my table, and these values for R from the van der Waals equation.

(for O2, a= 1.360 L2 atm/mol 2, and b= 31.83 cm3 / mol).

answer questions 14, 15, and 16. Please explain, i want to understand this. Is the uncertainty in R the error analysis?!

thanks!
