At standard temperature and pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. To find the number of moles of methane gas in 32 liters, you can use the formula: moles = volume (L) / volume per mole (L/mole). Thus, the calculation is 32 L / 22.4 L/mole = approximately 1.43 moles of methane gas.
This volume is 79,79 litres.
0.25 moles
Ideal gas equation. PV = nRT ===============
The volume is approx. 15,35 litres.
16.0 grams of methane (CH4) is equivalent to about 0.92 moles of methane, since the molar mass of methane is approximately 16.04 g/mol. In terms of molecules, this would be approximately 5.53 x 10^22 molecules of methane.
This volume is 79,79 litres.

At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 liters. Therefore, 5.6 liters of methane is equal to 5.6/22.4 = 0.25 moles of methane.

1) First find the number of moles of methane in 27.8 g using the molar mass.See the Related Question to the left of this answer "How do you convert from grams to moles and also from moles to grams?" to do that.2) Then write the balanced reaction. Methane (CH4) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). See the related question "How do you balance a chemical reaction?" to do that.3) That will tell you the ratio of moles of methane to moles of oxygen (it will be 2 to 1). So from Part 1, multiply the number of moles of methane by 2 to get moles of oxygen. Then, use the Ideal Gas Law to find out how many liters that will take up at STP. Use the Related Question link "How do you solve Ideal Gas Law problems?" to do that.
1 mole occupies 22.4 liters. 0.5 moles occupies 11.2 liters at STP.
At standard temperature and pressure, 1 mole of any gas will occupy 22.4 liters. Set up a direct proportion of 22.4 liters/1 mole = 1 liter/x moles and solve for x. You get 0.045 moles.
At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 liters. So, in 30 liters of methane, there would be 30/22.4 = 1.3393 moles. One mole of methane contains 6.022 x 10^23 molecules, therefore 30 liters of methane at STP would contain 1.3393 * 6.022 x 10^23 = 8.07 x 10^23 molecules.
1 mole occupies 22.414 liters So, 3.30 moles will occupy 73.966 liters.
The amount of oxygen is 0,067 moles.
