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 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 dichloromethane result from reaction of 1.54kg of methane if the yield is 48.2?
To calculate the grams of dichloromethane produced, we first need to convert the mass of methane from kilograms to grams, which is 1,540 grams. Given a yield of 48.2%, we can multiply this by the yield percentage to find the actual amount of dichloromethane produced: 1,540 grams of methane x 0.482 = 742.28 grams of dichloromethane.
The equation for the production of methane is C plus 2H2grams yields CH4grams How many liters of hydrogen are needed to produce 20 L of methane?
To produce 1 mole of methane (CH4), you need 2 moles of hydrogen (H2). Since 22.4 L of hydrogen is equivalent to 1 mole at standard temperature and pressure (STP), you would need 44.8 L of hydrogen to produce 1 mole of methane. Therefore, to produce 20 L of methane, you would need 896 L of hydrogen.
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.
How many grams of hydrogen are there in 16 grams of methane gas?
First you need atomic masses. Then you need to add them up to find the molecular mass of methane (CH4).Carbon = 12.0 gramsHydrogen = 1.0×4 = 4.0 grams--------------------------------------Methane = 16.0 gramsNow 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 hydrogenNow 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 grams of hydrogen are in 5.60 moles of methane?
There are 67.2 grams of hydrogen in 5.60 moles of methane. Methane (CH4) has one carbon atom and four hydrogen atoms, so the molar mass of CH4 is 16 grams/mol (carbon) + 4 grams/mol (hydrogen) = 20 grams/mol. In 5.60 moles of CH4, there are 5.60 moles x 4 mol of hydrogen/mol of CH4 = 22.4 moles of hydrogen. Finally, converting moles to grams, 22.4 moles x 1 gram/mol = 67.2 grams of hydrogen.
How many grams Four moles of methane would have a mass of how many grams?

How many atoms of hydrogen are in one molocule of methane?
4, as indicated by the subscript on the symbol for hydrogen in the formula for methane, CH4.
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.
How many moles of hydrogen are present in 3 moles of methane?
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
