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 molecules are in 30 liters of methane (ch4)?
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.
How many hydrogen atoms are there in 3.50 grams of methane?
3.5 g CH4 x 1 mole/16 g x 6.02x10^23 molecules/mole x 4 H atoms/molecule = answer.
What is the mass of 0.2 moles of methane?
16 grams per mole. Methane is CH4. Look at the Periodic table: Carbon is 12 grams/mole and Hydrogen is 1 gram/mole, so 1*12 + 4*1 = 16.
How many methane molecules of Ch4 have a mass equal to 3.20 grams?
One mole is equal to 6.022 x 1023 of anything. In this case, we are looking for molecules. So 1 mole=6.022 x 1023 molecules. We have 2.3 moles, so we want to know how many molecules are there. 2.3 mol CH4 x 6.022x1023 molecules CH4 / mol CH4 = 1.38x1024 molecules of CH4
How many H2O molecules are contained in 1 mole?
Because they are.
How many molecule's of carbon there are in 2.50 molecule's of methane?
Moles of methane. No half molecules, I think! 2.50 moles methane (1 mole C/1 mole CH4)(6.022 X 1023/1 mole C) = 1.51 X 1024 molecules of carbon --------------------------------------------
How many molecules of methane are in .123 moles of methane?
There are approximately 4.68 x 10^22 molecules of methane in 0.123 moles of methane. This is calculated using Avogadro's number, which is 6.022 x 10^23 molecules per mole.
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.
How many molecules are contained in 1 mole of water?
This is the number of Avogadro: 6,022 140 857(74).10e23.
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 atoms are present in a mole of methane?
Each molecule of methane contains one carbon atom, as shown by the formula for methane, CH4. Therefore, the number of carbon atoms in one mole of methane is the same as Avogadro's Number, about 6.022 X 1023.
How many molecules are in 30 liters of methane (ch4)?
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.

How many hydrogen atoms are there in 3.50 grams of methane?
3.5 g CH4 x 1 mole/16 g x 6.02x10^23 molecules/mole x 4 H atoms/molecule = answer.
One centimeter cube of methane at STP will have how much molecules?
One centimeter cube of methane at STP will contain approximately (2.42 \times 10^{19}) molecules. This is because one mole of any gas at STP occupies 22.4 liters, so 1 cm^3 of methane is equal to (1/(22.4 \times 10^6)) moles, and a mole of methane contains 6.022 x 10^23 molecules.
True or false a mole of water in chemistry contains the same number of atoms as a mole of methane?
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
How many atoms are in one mole of methane?
