In the chemical formula ( CH_4 ), there are 4 hydrogen atoms per molecule of methane. Therefore, in 3 moles of ( CH_4 ) (represented as ( 3CH_4 )), there would be ( 3 \times 4 = 12 ) hydrogen atoms.
16 grams of oxygen how many moles is 0,5 moles.
moles of what?
2 moles of Ca and 4 moles of OH
The answer is 10 moles.

There are 16 atoms in 3CH4, which consists of 3 molecules of methane (CH4). Each methane molecule contains 5 atoms - one carbon atom and four hydrogen atoms. So, 3 molecules of CH4 contain a total of 3 carbon atoms and 12 hydrogen atoms, giving a total of 16 atoms.
The Chemical equation tells you 3CH4 the first 3 tell you that there are 3 molecules of CH4 CH4 has 1 Carbon and 4 hydrogen (it is called methane) making a total of 5 atoms and there are 3 of them so there is a total of 15 atoms. EDIT (by Dr.J.): Not correct. If there are 3 moles as stated, each mole contains 6.02x10^23 molecules and each MOLECULE contains 5 atoms, so the CORRECT answer is (15)(6.02x10^23) = 9x10^24 atoms
c6H12O6 + 3hco3- + 3h+ >>> 6co2 + 3h20 + 3ch4
16 grams of oxygen how many moles is 0,5 moles.
Of course 6 moles.
moles of what?
55.8 moles
2 moles of Ca and 4 moles of OH
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
this is a easy one. There are only 0.04166 moles.
The answer is 7,73 moles.
