The student diluted 2.000 mL of 4.000 M K 2 CO 75.0 mL, then combined that solution with 75.00 mL of 2.000 M H an increased temperature of 50 °C. The student tabulated the amount of CO 2 gas collected over time recorded the results in the columns to the left. 1. Use a rearrangement of PV = nRT to solve for the number of m of CO 2 produced. You may assume atmospheric pressure. Enter ( fill down) your formula in column C. 2. Make a scatter plot of moles of CO 2 versus time. Make sure th has the following features: -y axis shows moles CO 2 , x axis shows time in minutes

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
