How many grams of H are in 1 mole of methane?
I don't understand this. I got 16.1 but it's wrong. Any help is much appreciated

Huh?
Methane = CH4
C = 12 grams per mole
H = 1 gram per mole
so CH4 = 16 grams/mole of which 4 are H
so 4 grams

Damon has said it very well. Here is another way to look at it.
mols H = 1 mol CH4 x (4 mols H/1 mol CH4) = 4
Then grams H atoms = 4 mols H atoms x (1 g H/mol H) = 4 grams

To determine the number of grams of hydrogen (H) in one mole of methane (CH4), we need to use the molar mass and the stoichiometry of the compound.
Methane (CH4) consists of one carbon atom (C) and four hydrogen atoms (H). The molar mass of carbon is 12.01 g/mol, and the molar mass of hydrogen is 1.008 g/mol.
To calculate the molar mass of CH4, we sum up the molar masses of each element:
Molar mass of CH4 = (molar mass of C) + (molar mass of 4H)
= (12.01 g/mol) + (4 * 1.008 g/mol)
= 16.04 g/mol
Therefore, one mole of methane (CH4) has a molar mass of 16.04 g/mol.
Now, to find the grams of hydrogen (H) in one mole of methane (CH4), we need to consider the ratio of the number of moles of hydrogen to the number of moles of methane.
The ratio of hydrogen moles to methane moles is 4:1, which means for every one mole of methane, there are four moles of hydrogen.
To find the grams of hydrogen in one mole of methane, we multiply the molar mass of hydrogen by the ratio of hydrogen moles to methane moles:
Grams of hydrogen (H) = (molar mass of H) * (ratio of H moles to CH4 moles)
= (1.008 g/mol) * (4/1)
= 4.032 g/mol
Therefore, there are 4.032 grams of hydrogen in one mole of methane (CH4).
I hope this explanation helps clarify the calculation process.
