The number of atoms of an element in a molecule is the number subscript immediately following the element symbol in the formula for the molecule. The number of moles of anything in a compound depends on the amount of the compound, which is not stated.
To convert atoms to moles, you divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 1.53 x 10^24 atoms of carbon divided by Avogadro's number is equal to 2.54 moles of carbon.
The number of moles of carbon in 11,5 g of ibuprofen is 0,725.
To convert from molecules to moles, divide the number of molecules by Avogadro's number (6.022 x 10^23). So, for 5.01020 molecules of carbon, the number of moles of carbon would be approximately 8.33 x 10^-3 moles.
The number of grams in 20 moles of carbon is 240,22 g.
To convert from molecules to moles, divide the given number of molecules by Avogadro's number, which is 6.022 x 10^23. Therefore, for 2.22 x 10^23 molecules of carbon dioxide, divide by Avogadro's number to find 0.368 moles of carbon dioxide.
To find the number of hydrogen atoms in 2 grams of cholesterol, you need to first calculate the molar mass of cholesterol (about 386 g/mol) and then divide the given mass by the molar mass to find the number of moles. Next, use the molecular formula of cholesterol (C27H46O) to determine the number of hydrogen atoms in one mole of cholesterol. Finally, multiply this number by the number of moles to find the total number of hydrogen atoms present in 2 grams of cholesterol.
To convert atoms to moles, you divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 1.53 x 10^24 atoms of carbon divided by Avogadro's number is equal to 2.54 moles of carbon.

To convert from molecules to moles, divide the number of molecules by Avogadro's number (6.022 x 10^23). So, for 5.01020 molecules of carbon, the number of moles of carbon would be approximately 8.33 x 10^-3 moles.
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.
The number of grams in 20 moles of carbon is 240,22 g.
To convert from molecules to moles, divide the given number of molecules by Avogadro's number, which is 6.022 x 10^23. Therefore, for 2.22 x 10^23 molecules of carbon dioxide, divide by Avogadro's number to find 0.368 moles of carbon dioxide.
The mass of 4,5 moles of carbon is 54,04815 g.
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.
There are 6.022 x1023 atoms of carbon per mole. So 2.85 * 6.022x1023 is the answer ... 1.72 x1024 atoms of carbon.
10 moles of calcium has more atoms than 10 moles of carbon, as calcium has a higher atomic number and atomic weight compared to carbon. Each mole contains Avogadro's number of atoms, so the element with the larger atomic weight will have more atoms in 10 moles.
Quinine is a compound made up of several elements, including carbon. To determine the exact number of moles of carbon in quinine, you would need to know the molecular formula of quinine, count the number of carbon atoms in the formula, and then calculate the moles using Avogadro's number and the molar mass of carbon.
