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 find the number of moles of carbon in cholesterol (C27H46O), you first need to calculate the molar mass of the molecule. By adding up the atomic masses of carbon in the compound, you find the total molar mass of carbon in the molecule. From there, you can use the molar mass of carbon to convert it to moles.

Convert 1.53 x 1024 atoms of carbon to moles of carbon?
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.
How many moles of Carbon are in G of ibuprofen?
The number of moles of carbon in 11,5 g of ibuprofen is 0,725.
How many moles of carbon is contained in 5.01020 molecules 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.
Which value most closely represents the number of grams in 20 moles of carbon?
The molar mass of carbon is approximately 12 grams per mole. Therefore, 20 moles of carbon would be around 240 grams.
How many moles of carbon dioxide are in 2.22 1023 molecules of carbon dioxide?
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.
How many hydrogen atoms present in 2grams cholesterol?
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.

What is the mass in grams of 4.5 moles of carbon?
The molar mass of carbon is 12.01 g/mol. To find the mass of 4.5 moles of carbon, you would multiply the molar mass by the number of moles: 4.5 moles * 12.01 g/mol = 54.045 grams.
How many moles of carbon dioxide are there in 19 grams of carbon dioxide?
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.
How many carbon dioxide molecules are there in 7.30 moles of carbon dioxide?
To find the number of molecules in 7.30 moles of carbon dioxide, you would multiply Avogadro's number (6.022 x 10^23 molecules per mole) by the number of moles. Therefore, there are 7.30 * 6.022 x 10^23 molecules of carbon dioxide in 7.30 moles.
How many atoms of carbon are present in 2.85 moles of carbon?
There are 1.72 x 10^24 atoms of carbon in 2.85 moles of carbon. This is calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles.
Which has more atoms 10 moles of carbon or 10 moles of calcium?
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.
How many moles of carbon are quinine?
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.
