Question

A student conducted an experiment to determine what factors areimportant in the rate of a reaction between potassium carbonate andhydrochloric acid. The student diluted 4.000 mL of 4.000 MK2CO3 to 75.00 mL, then combined thatsolution with 75.00 mL of 2.000 M HCl.

The student tabulated the amount of CO2 gas collected over time andrecorded the results below:

Time(min)...Vol(mL)...
1... 0.6
2... 1.2
3... 1.8
4... 2.4
5... 3
6... 3.6
7... 4.2
8... 4.8
9... 5.4
10... 6
11... 6.7
12... 7.3
13... 7.9
14... 8.5
15... 9.1
16... 9.7
17... 10.3
18... 10.9
19... 11.5
20... 12.1




Use a rearrangement of PV = nRT to solve for the number of moles ofCO2 produced. You mayassume atmospheric pressure and room temperature.

any ideas?

Explanation / Answer

number of moles can be found using the followingformullae                                                       Noof Moles= mass of solute/Molar Mass
