how many moles of carbon are in 440 mg of co2?
7084
But also 440 gCO2 contains less than 0.01 mole: 0.0099979 mole if you count the average isotopes.
978218
The mass number of CO2 = 2x16 + 12 =44 so one mole of C02 has a mass of 44g. Two moles of CO2 weighs 2 x 44 = 88g. The number of moles in 22g of CO2 = 22/44 = 0.5. One mole always contains the same number of particles which is given by avagadro's number.

As citric acid and carbon dioxide are in a 1:3 ratio in the chemical equation, 0.0052 moles of citric acid will result in 0.0052*3, or 0.0156 moles of carbon dioxide.

There are 2.33 moles of carbon in 28 grams of carbon sample. Explanation: To know the number of moles in a given mass of a substance, we can use the definition of mole.

Avogadro's number shows us that there are 6.022 x 10^23 molecules of CO2 in 1 mole of the gas. Therefore, there are 6.022 x 10^23 atoms of carbon and 12.044 x 10^23 atoms of oxygen in that 1 mole of CO2.
1189855
Therefore, the number of molecules in 2.5 moles of CO2 would be: (6.022 X 10^23 X 2.5)=1.5055 X 10^24 molecules of carbon (IV) oxide.

Answer and Explanation: The mass of one mole of CO2 is 44.01 grams. There are 6.022 X 1023 molecules of CO2 in a mole, enough to make the grams in the mole equal the mass...

mass % C = (mass of 1 mol of carbon/mass of 1 mol of CO2) x 100. mass % C = (12.01 g / 44.01 g) x 100. mass % C = 27.29 %

1 mol of CO2 weighs 44g. There is one carbon atom in each molecule of CO2. So the answer is 3.01 x 10 to the 23rd carbon atoms in 22 g of CO2.
790125
Answer and Explanation: A mole of CO2 contains 12.044 X 1023 oxygen atoms. We can find this answer by first determining how many molecules of CO2 we have in a mole. A mole is...

3. The production of 23 moles of carbon dioxide required 34.5 moles of oxygen gas.
1386182
Answer : The number of moles of carbon dioxide is 4.795 moles. Therefore, the number of moles of carbon dioxide is 4.795 moles.

1 Answer. The moles of carbon dioxide produced from 100 g methane is 6 moles.
1010214
A mole of CO2 is 44 grams. So 8 grams is 8/44 = 0.1818… moles, or four elevenths.
1348936
So, 44 g of CO2 will contain 6.023x 10 ^ 23 molecules. Since in 1 mole of CO2 6.022*10^23 molecule exist whose mass is 44g hence in 8.8g of CO2 0.2 mole of molecules i.e 12.044*10^22 molecules will be present. There are 1.2046×10^23 number of molecules of CO2 in 8.80 g of CO2.

There is ONE CARBON ATOM, that is 6 electrons; and TWO OXYGEN ATOMS, that is 16 electrons, i.e. 22 electrons per molecule. Moles of carbon dioxide = 100⋅g44.01⋅g⋅mol−1=2.27⋅mol .
