1.

Based on Figure 2, how many grams of CO would the chemist have to add to the 10 L vessel in order to create approximately 50 kPa of pressure inside the vessel?

Between 0 and 125 grams

Between 125 and 250 grams

Between 250 and 375 grams

Between 375 and 500 grams

2.

Suppose the chemist had repeated Steps 1-6 using a 7 L vessel. Based on Figures 1 and 2, the pressure created inside the vessel by 500 grams of oxygen gas would most likely have been:

less than 25 kPa.

between 25 and 100 kPa.

between 100 and 175 kPa.

greater than 175 kPa.

3.

Based on Figures 1 and 2, for a given mass of H2 at 23 °C, how does the pressure created by the H2 gas in the 5 L vessel compare to the pressure created by the H2 gas in the 10 L vessel? In the 10 L vessel, the pressure will be:

1/2 as great as in the 5 L vessel.

1/3 as great as in the 5 L vessel.

the same as in the 5 L vessel.

2 times as great as in the 5 L vessel.
