First you need atomic masses. Then you need to add them up to find the molecular mass of methane (CH4).
Carbon = 12.0 grams
Hydrogen = 1.0×4 = 4.0 grams
--------------------------------------
Methane = 16.0 grams
Now that you know the total mass, you can figure out how much of the compound is actually hydrogen (by percent). So you take the mass of hydrogen and divide it by the total mass of methane.
4.0 ÷ 16.0 = .25 = 25% of methane is hydrogen
Now we take the 16 grams and figure out how much of that 16 grams is hydrogen. We know that 25% of it is hydrogen, so take one-fourth of 16 to get 4. But sometimes the numbers aren't as easy and you have to multiply them out.
25% of 16 = .25 × 16 = 4 grams hydrogen

How many moles of hydrogen gas are in 5.04 grams in hydrogen gas?
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.
How many moles are in 18.0grams of hydrogen gas?
To find the number of moles in 18.0 grams of hydrogen gas, you need to divide the given mass by the molar mass of hydrogen gas. The molar mass of hydrogen gas (H2) is about 2.016 grams/mol. So, 18.0 grams / 2.016 grams/mol ≈ 8.93 moles of hydrogen gas.
How many molecules in 10 grams of methane?
Find out the percentage of hydrogen in the molar mass of methane. Molar mass of CH4: C = 1 * 12.01 g = 12.01 g H = 4 * 1.01 g = 4.04 g Total = 16.05 g 4.04 g/16.05 g * 100% = 25.171% 0.25171 * 20 g = 5.0342 g There are about 5.03 grams of hydrogen in 20 grams of methane gas.
Are methane gas and ammonia the same?
No, methane gas (CH4) and ammonia (NH3) are not the same. Methane is a hydrocarbon gas composed of carbon and hydrogen atoms, while ammonia is a compound made of nitrogen and hydrogen atoms. They have different chemical compositions and properties.
What type of gas is Methane?
Methane gas is a greenhouse gas used in most industries. It is an alkane (compound with CO2 and hydrogen particles).
How many grams of hydrogen are there in thirty grams of methane gas?
8 grams. Or more exactly, in 30.0 grams of methane there is 7.54 grams of hydrogen.
How many hydrogen atoms are in 45.0 grams of hydrogen gas?
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
How many moles of hydrogen gas are in 5.04 grams in hydrogen gas?
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.
How many elements in methane gas?
the chemical formula of methane is CH4. one molecule of methane contains one carbon atom and four hydrogen atoms.
How many grams of oxygen are there in 17800 grams hydrogen sulfate?
It is not measured in grams but PPM because it is a gas.
How many moles are in 18.0grams of hydrogen gas?
To find the number of moles in 18.0 grams of hydrogen gas, you need to divide the given mass by the molar mass of hydrogen gas. The molar mass of hydrogen gas (H2) is about 2.016 grams/mol. So, 18.0 grams / 2.016 grams/mol ≈ 8.93 moles of hydrogen gas.
