The gram Atomic Mass of carbon is 12.011. Therefore, 1.1 grams constitutes 1.1/12.011 or about 0.0908 moles of carbon. The number of atoms is then 0.0908 X Avogadro's Number or 5.5 X 1022 atoms, to the justified number of significant digits.
5.02 x 10^23 atoms C
I arrived at this answer by setting up a conversion factor, using Avogardro's number (6.022x10^23) and the atomic mass of Carbon rounded to the nearest whole number (12g). I then rounded my own answer to maintain the 3 significant figures of 10.0. When you do so you arrive at this equation:
10.0g C X (1mol C/ 12 g C) X (6.022x10^23/ 1 mol C) = 5.02 x 10^23 atoms C
no.moles of carbon = mass/relitive molecular mass = 10/12 = 0.833
no atoms in a mole = 6.022 x 1023, and we have 0.833 of a mole = 5.0183 x 1023 atoms in 10g of carbon.
12.0107 amu (not grams)
It is just larger than 12 due to a small amount of carbon-13 in natural carbon.

Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
C = 1 * 12.01 g = 12.01 g O = 2 * 16.00 g = 32.00 g CO2 = 44.01 g (12.01 g/44.01 g) * 100% = 27.289% 0.27 * 88 g = 23.76g Or more accurately.. 0.27289 * 88 g = 24.01 g There is about 24 grams of carbon in 88 grams of carbon dioxide.
The formula for sucrose is C12H22O11. This means for every 342.30 g (1 mole) of sucrose there are 144 g of carbon (12 moles) or 42.1 g per 100 g.
No. 100 lead atoms are several times heavier than 100 aluminum atoms.

For carbon 0.80 x 100 = 80 grams of carbon; and for hydrogen 0.20 x 100 = 20 grams of hydrogen
100 atoms of C-12(12g/6.022x10^23) = 1.993x10^-21g
100 grams zinc (1 mole Zn/65.41 grams)(6.022 X 1023/1 mole Zn) = 9.21 X 1023 atoms of zinc ------------------------------------
moles = mass (g) divided by the molecular weight (g/mol) moles = 100g/12.01
100 grams = 3.5 ounces.
100 grams is 3.527 ounces.

By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.
yes, diamond is made of carbon. Diamond is a macromolecule made of many carbon atoms. Each carbon atom is joined to 4 more carbon atoms each. Having each atom of carbon bonded to four other atoms is why diamond is so hard- there are lots of strong chemical bonds to overcome.
