The questions asks how many moles of carbon atoms.
Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.
How many atoms are in 36 grams of Carbon?
[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
There are 1.9 grams of Carbon. The molar mass of carbon is approximately 12 grams per mole. This means there are ~0.158 moles of carbon. Since 1 mole of carbon contains Avogadro's number of atoms (~6.022 x 10^23 atoms), then 0.158 moles would contain ~9.53 x 10^22 atoms.
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.
The molecular weight of Novocaine/Procaine (C12H21N2O2Cl) is 236.3 grams per mole. Each molecule of Novocaine contains 12 moles of carbon (C). 1.574 grams of Novocaine equals .006661 moles. Therefore, .07993 moles of C are to found in this sample size.
5 moles carbon? 5 grams carbon? Both done. 5 moles carbon (6.022 X 1023/1 mole C) = 3.0 X 1024 atoms carbon =================== 5 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 2.5 X 1023 atoms carbon ==================== your choice
0,666 moles
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
There are 1.9 grams of Carbon. The molar mass of carbon is approximately 12 grams per mole. This means there are ~0.158 moles of carbon. Since 1 mole of carbon contains Avogadro's number of atoms (~6.022 x 10^23 atoms), then 0.158 moles would contain ~9.53 x 10^22 atoms.
There are 12 carbon atoms in one molecule of sugar (C12H22O11). Therefore, in 2 moles of sugar, there would be 12 * 2 * 2 = 48 moles of carbon. To convert moles to grams, you would multiply the number of moles by the molar mass of carbon (12 g/mol), so there would be 48 * 12 = 576 grams of carbon in 2 moles of sugar.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
There are 9.33 moles of carbon in 5.62 atoms of carbon.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
