To find the number of molecules in 30 liters of methane (CH₄), we can use the ideal gas law, which states that 1 mole of gas occupies 22.4 liters at standard temperature and pressure. Therefore, 30 liters of methane is approximately 1.34 moles (30 L / 22.4 L/mol). Since one mole contains about (6.022 \times 10^{23}) molecules (Avogadro's number), 1.34 moles of methane contains approximately (8.06 \times 10^{23}) molecules.
What else can I help you with?
How many molecules of oxygen 2 are needed to react with which molecule of methane CH4?
To react completely with one molecule of methane (CH4), two molecules of oxygen (O2) are needed. This is because the balanced chemical equation for the combustion of methane is CH4 + 2O2 → CO2 + 2H2O. Each molecule of methane requires two molecules of oxygen to form carbon dioxide and water.
Description of 16.0 grams of methane?
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.
How many grams of methane gas CH4 are contained in a volume of 144 liters at STP?
At STP (standard temperature and pressure), one mole of any gas occupies 22.4 liters. This means that 144 liters of methane gas contain 144/22.4 moles of CH4. Using the molar mass of CH4 (16 g/mol), you can calculate the mass of methane gas in grams.
Which molecule has a tetrahedral molecular geometry?
There are many, but the most common is methane (CH4).
What is the abbreviation of methane?
The chemical symbol for methane is CH4.
How many molecules are in 30 liters of methane (CH4) at STP?
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.

It represent a one molecule.CH4 stands for Methane
How many molecules of H2O and CO2 can be made from 4 molecules of CH4 and excess O2?
The balanced equation for the combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2O4 molecules of CH4 will produce 4 molecules of CO2 and 8 molecules of H2O

What is the coefficient of 2 CH4?
The meaning of 2 is two methane molecules.
Which molecule has a tetrahedral molecular geometry?

How many liters of hydrogen gas are needed to react with CS2 to produce 2.5L of CH4 at STP?
The balanced equation for the reaction between hydrogen gas (H2) and carbon disulfide (CS2) to produce methane (CH4) is: 4H2 + CS2 → 4H2S + CH4. This means that for every 4 moles of hydrogen gas, 1 mole of methane is produced. Since 1 mole of any gas at STP occupies 22.4 liters, you would need 5.6 liters of hydrogen gas to produce 2.5 liters of methane.
How many moles of methane CH4 are present in 5.6L of the gas at STP?
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.
When methane burns in air the bonds in methane molecules and oxygen molecules are broken?
Yes; the reaction is: CH4 + 2 O2 = CO2 + 2 H2O
What is the abbreviation of methane?
The chemical symbol for methane is CH4.
