Solution : 16g methane `(CH_(4))` represent 1 mole and has `6.02xx10^(23)` molecules of methane.
16.043 gramsAn amount of any substance in grams that is numerically equal to its atomic or molecular weight in amu has been defined as one mole of that substance. By this definition, one mole of hydrogen is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams.
4gm of Hydrogen is the answer.
16 uMolecular mass of methane (CH4) = atomic mass of C + (4 × atomic mass of H) = 12 + (4 × 1) = 16 u.
0.50 molesThe number of moles of methane in 8.0 grams is 0.50 moles.
3.01×1023 atomsNumber of atoms present in 1.6 g of methane is: 6.02×1023 × (1.6g/16g/mol)×5 = 3.01×1023 atoms. Was this answer helpful?
More specifically, a mole of methane contains 6.022⋅1023 molecules of methane - this is known as Avogadro's number.
Solution : 1 mole of `CH_4" contains "4xx6. 023xx10^(23)=2.408xx10^(24)` atoms of hydrogen atoms and `6.023xx10^(23)` atoms of carbon atoms. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
0:212:29How to Convert Moles of CH4 to Grams - YouTubeYouTubeStart of suggested clipEnd of suggested clipIt's also our conversion factor that we'll use to convert moles of ch4 to grams. So we take 2.12MoreIt's also our conversion factor that we'll use to convert moles of ch4 to grams. So we take 2.12 moles abbreviated mol of ch4. And we'll multiply that by the molar mass this 16.05 grams per mole.
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
≈3.34×1022.
