Diamonds are all carbon. just divide 1200 grams by 12.01 grams per mole carbon.
The Cullinan diamond is made up of pure carbon in the form of diamond. The diamond's weight is approximately 3106 carats, which is equivalent to about 0.62 kg. Using the molar mass of carbon (12.01 g/mol), the Cullinan diamond contains about 4.1 x 10^23 carbon atoms, which is approximately 683 moles of carbon.
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
A carat is a unit of mass equal to 200 milligrams, so 1000 carats is 200 grams. Since diamond is a form of carbon, its molecular structure consists solely of carbon atoms. The molar mass of carbon is approximately 12 grams per mole, which means 200 grams of diamond contains about 16.67 moles of carbon, equating to roughly 1.00 x 10^24 carbon atoms.
A 2.3-carat diamond contains approximately 0.46 grams of carbon, as one carat is equivalent to 0.2 grams. Since the molecular weight of carbon is about 12 grams per mole, this translates to about 0.038 moles of carbon. Given that one mole of carbon contains approximately 6.022 x 10²³ atoms, a 2.3-carat diamond has roughly 2.3 x 10²² carbon atoms.
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
The Cullinan diamond is made up of pure carbon in the form of diamond. The diamond's weight is approximately 3106 carats, which is equivalent to about 0.62 kg. Using the molar mass of carbon (12.01 g/mol), the Cullinan diamond contains about 4.1 x 10^23 carbon atoms, which is approximately 683 moles of carbon.
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.
To find the number of moles of carbon in a 1.50-carat diamond, first convert carats to grams: 1.50 carats * 0.200 g/carat = 0.30 g. Then, calculate the number of moles using the molar mass of carbon (12.01 g/mol): 0.30 g / 12.01 g/mol ≈ 0.025 moles of carbon.
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
The number of grams in 20 moles of carbon is 240,22 g.
moles = weight in grams / molecular weight = 56 / 28 = 2 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.
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles carbon ===============
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
0,666 moles
The mass of 4,5 moles of carbon is 54,04815 g.
