Question

Volume and Moles Part A Avogadro's law states that the volume, V, of a gas is directly related to the number of moles, m, of the gas when temperature and pressure are constant: (Figure 1) A cylinder, with a piston pressing down with a constant pressure, is filled with 2.10 moles of a gas (1), and its volume is 50.0 L (Vi). If 0.800 mole of gas leak out, and the pressure and temperature remain the same, what is the final volume of the gas inside the cylinder? Express your answer with the appropriate units where Vi is the volume filled by n1 moles and V2 is the volume filled by a different number of moles, n2 Hints v2-Value Units Figure 1 of 1 Submit My Answers Give Up Part B A sample of gas in a cylinder as in the example in Part A has an initial volume of 50.0 L,and you have determined that it contains 1.30 moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 12.5 L. How many moles of gas (2) remain in the cylinder? Express your answer with the appropriate units Hints Fewer moles Smaller volume More moles Larger volume n2= 1 Value Units Suhmit

Explanation / Answer

A)

we have:

V1 = 50.0 L

n1 = 2.10 mol

n2 = 2.10 - 0.80 = 1.30 mol

we have below equation to be used:

V1/n1 = V2/n2

50.0 L / 2.10 mol = V2 / 1.30 mol

V2 = 31.0 L

Answer: 31.0 L

B)

we have:
n1 = 1.30 mol
V1 = 50.0 L
V2 = 12.5 L

we have below equation to be used:
V1/n1 = V2/n2
50.0 L / 1.30 mol = 12.5 L / n2
n2 = 0.325 mol

Answer: 0.325 mol
