To determine this we must first know what the molar mass of Carbon is and that equals 12.01g. This mean for every 12.01g of Carbon, we have one mole. Therefore:
From the Periodic Table, the Atomic Mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 48/12.0 = 4.0mol
There are 4.0 moles of carbon in a 48g pure sample.
12g of carbon = one mole of carbon.
1g =1/12 moles
24g = 1/12 24x =2moles
1 mole of carbon is 12 grams
divide 38/12 = 3.17 moles
number of moles = mass/molecular mass. = 24/12 = ~2 moles
48/12 = 4 moles of C atoms are in 48g of carbon-12.
So there are 4 x 6.022 x 1023 = 2.4088 x 1024 total atoms.
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 moles of carbon in 11,5 g of ibuprofen is 0,725.
10 g of carbon is equivalent to 0,8326 moles.
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles carbon ===============
12 (one carbon) + 2*16 (two oxygens) = 48g/mol
KCl has a molar mass of 39+35.5=74.5g/mol, and 48/74.5=0.64mol.
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
211g of carbon dioxide are equal to 4,794 moles.

3.5 moles CaCO3 (1 mole carbon/1 mole CaCO3) = 3.5 moles
10 g of carbon is equivalent to 0,8326 moles.
0,515 g of carbon is equal to 0,043 moles.
The number of moles of carbon in 11,5 g of ibuprofen is 0,725.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
There are 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
