atomic weight of carbon dioxide is 2 * 16 + 12 = 44
1 kg = 1000 g
1 kg of co2 has 1000/44 = 22.7 moles
yeh i think that's wrong lol
isn't it 3.37E25?
See, the formaula for calculating number of moles is, weight per mol. wt. of element or compound. Therefore, No. of KG moles equals 1 / 44 KG
44 gram in one mole of CO2
(44 = 12 + 2*16)
The weight of one mole of carbon dioxide is 44,01 g.
1 gram is equal to 0.0227 moles.
The equivalent of 1,78 kg of carbon dioxide is 40,44 moles.
CO2 is 1 mole. It comprises of 44 grams.
The molar mass of carbon dioxide is 44,01 g.
Number of moles = mass of CO2/molar mass.
1 mole of CO2 contain...1 mole ! And this mole has 44,01 g.
100 grams of carbon dioxide contain 2,27 moles.
1 mole contains 6.023 times 10^23 atoms....so ......2 moles ...that would be 2 times 6.023 times 10^23 got it?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------

2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
One molecule of N2O N 2 O contains one atom of oxygen.
1 mole contains 6.023 times 10^23 atoms....so ......2 moles ...that would be 2 times 6.023 times 10^23 got it?
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
One femtomole is a billionth of a million (10-15) of a mole. One mole contains 6.02214078×1023 molecules, therefore we multiply one mole by 2 femtomoles: 6.02214078 x 1023 x10-15 x2= 1204428156 molecules of protein
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------

Remember the equation Moles = mass(g) / Relative Atomic/molecular mass (Ar/Mr) moles = mass(g) / Ar/Mr The mass is 14 g The Mr for CO is:- From the Periodic Table Mass of C = 12 and mass of O = 16 12 + 16 = 28 Substituting moles(CO = 14g / 28 moles = 0.5 ( or 1/2 mole)
2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
Each mole of PbO2 contains 2 moles of oxygen (O). Thus there would be 5.43x2 = 10.86 moles O.Each mole of water (H2O) contains 1 mole of O, so from 10.86 moles of O you could get 10.86 moles of H2O.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
