4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
This is carbon tetra chloride. there are 0.3636 moles in this mass.
To determine the number of moles in 10 g of carbon, you need to know the molar mass of carbon, which is approximately 12 g/mol. By dividing the given mass by the molar mass, you can calculate that there are approximately 0.83 moles of carbon in 10 g.
80,0 moles of CO2is equal to 3 520,8 g.
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
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.
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
Since there is one carbon atom per mole in carbon tetrafluoride, the answer is 3.27 times Avogadro's Number or about 1.97 X 1024 atoms.
To determine the number of moles of carbon in the original sample, you need to know the mass of carbon present and its molar mass, which is approximately 12.01 g/mol. You can calculate the number of moles using the formula: moles = mass (g) / molar mass (g/mol). If you have the mass of carbon from the sample, simply divide that value by 12.01 g/mol to find the number of moles.
211g of carbon dioxide are equal to 4,794 moles.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
