Question

1.) A cylinder with a moveable piston contains 0.81 mol of gas and has a volume of 344 mL. What will its volume be if an additional 0.25 mol of gas is added to the cylinder? (Hint: The final number of moles is the sum of the initial number and the amount added.)

2.)A bag of potato chips contains 595 mL of air at 35.0 ∘C and a pressure of 775mmHg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 453 mmHg and the temperature is 10.0 ∘C?

3.)How many liters of hydrogen gas are formed from the complete reaction of 1.03 mol of C? Assume that the hydrogen gas is collected at a pressure of 1.0 atm and temperature of 319 K .

Consider the chemical reaction:
C(s)+H2O(g)→CO(g)+H2(g)

4.)Use Charles's law to complete the table. (Assume pressure and number of moles of gas to be constant.)

Part	V1	T1	V2	T2
A	112 L	10.4 ∘C	__	112.3 ∘C
B	__	138 K	179 L	315 K
C	2.07 L	15.6 ∘C	2.40 L	__
D	16.4 cm3	__	19.8 cm3	10.2 ∘C
