There are always ONE mole of gas in 22,4 L gas of any kind (even gaseous mixtures like air) at stp.
So 68.5 (L) / 22.4 (L/mole) = 3.06 mole gas in 68.5 L (at STP)
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
To convert from molecules to moles, divide the given number of molecules by Avogadro's number, which is 6.022 x 10^23. Therefore, for 2.22 x 10^23 molecules of carbon dioxide, divide by Avogadro's number to find 0.368 moles of carbon dioxide.
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
To find the number of moles, divide the number of molecules by Avogadro's number, which is (6.022 \times 10^{23}) molecules/mol. (3.75 \times 10^{24}) molecules of carbon dioxide is equivalent to 3.75 moles of carbon dioxide.
Multiply by avagadro constant. It is equals to 6.022*1^23
211g of carbon dioxide are equal to 4,794 moles.
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
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.
= 9403.41
6.32 mol carbon dioxide
To convert from molecules to moles, divide the given number of molecules by Avogadro's number, which is 6.022 x 10^23. Therefore, for 2.22 x 10^23 molecules of carbon dioxide, divide by Avogadro's number to find 0.368 moles of carbon dioxide.
The answer is 64,9 moles.
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
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.
To find the number of moles of carbon dioxide, you use the formula: Moles = Mass / Molar mass. The molar mass of carbon dioxide is about 44.01 g/mol. So, for 52.06 g of carbon dioxide, you would have Moles = 52.06 g / 44.01 g/mol, which equals approximately 1.183 moles.
To find the number of moles, divide the number of molecules by Avogadro's number, which is (6.022 \times 10^{23}) molecules/mol. (3.75 \times 10^{24}) molecules of carbon dioxide is equivalent to 3.75 moles of carbon dioxide.
