To find the mass of 455 mL of ethane (C₂H₆) gas at standard temperature and pressure (STP), we first note that 1 mole of any ideal gas occupies 22.4 liters (or 22,400 mL) at STP. Thus, 455 mL of ethane corresponds to approximately ( \frac{455}{22400} ) moles, which is about 0.0203 moles. The molar mass of ethane is about 30.07 g/mol, so the mass of 455 mL of ethane at STP is approximately ( 0.0203 , \text{moles} \times 30.07 , \text{g/mol} \approx 0.61 , \text{grams} ).

What is the chemical reaction when C2H6 gas is combusted?
The chemical reaction when C2H6 gas (ethane) is combusted is: 2C2H6 + 7O2 -> 4CO2 + 6H2O. Ethane reacts with oxygen to produce carbon dioxide and water.
Which has more entropy C2H6 gas or C6H14 gas?
C6H14 gas (hexane) will have more entropy than C2H6 gas (ethane) because hexane has a greater molecular complexity with more atoms and freedom of movement. This leads to more possible microstates and greater disorder, resulting in higher entropy.
How many grams of oxygen gas are required to completely react with 77.28 g of ethane (C2H6) in the balanced redox reaction 2 C2H6(g) 7 O2(g) 4 CO2(g) 6 H2O(g)?
To determine the grams of oxygen gas required to react with 77.28 g of ethane (C2H6), first calculate the moles of ethane. The molar mass of C2H6 is approximately 30.07 g/mol, so 77.28 g of C2H6 corresponds to about 2.57 moles of C2H6. According to the balanced reaction, 2 moles of C2H6 react with 7 moles of O2; thus, for 2.57 moles of C2H6, the required moles of O2 would be ( \frac{7}{2} \times 2.57 \approx 9.00 ) moles of O2. Finally, using the molar mass of O2 (approximately 32 g/mol), the mass of O2 needed is ( 9.00 , \text{mol} \times 32 , \text{g/mol} = 288 , \text{g} ).

What is the chemical reaction when C2H6 gas is combusted?
The chemical reaction when C2H6 gas (ethane) is combusted is: 2C2H6 + 7O2 -> 4CO2 + 6H2O. Ethane reacts with oxygen to produce carbon dioxide and water.
What is the ratio of the rates of diffusion of hydrogen gas to ethane gas C2H6?
According to Graham's Law of Effusion, the rate of diffusion of a gas is inversely related to the square root of the molar mass. Thus, smaller (lighter) gases diffuse faster than larger, heavier gases. Molar mass of H2 = 2 and molar mass of C2H6 = 30. Sqrt 2 = 1.41 and sqrt 30 = 5.48, so the ratio is 5.48/1.41 = 3.88 or H2 will diffuse almost 4x faster (3.88x) than ethane. The ratio of H2/C2H6 would be the inverse, or 1.41/5.48 = 0.257, meaning that the rate of diffusion of ethane is about 26% that of hydrogen.
Which has more entropy C2H6 gas or C6H14 gas?
C6H14 gas (hexane) will have more entropy than C2H6 gas (ethane) because hexane has a greater molecular complexity with more atoms and freedom of movement. This leads to more possible microstates and greater disorder, resulting in higher entropy.
