How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 88.1 moles of water vapor?
The balanced chemical equation for the reaction is 2H2 + CO2 -> 2H2O. This means that 2 moles of hydrogen gas react with 1 mole of carbon dioxide to produce 2 moles of water vapor. Therefore, to produce 88.1 moles of water vapor, 44.05 moles of hydrogen gas would be needed.
How many moles of carbon are present in a 100g sample?
To calculate the number of moles of carbon in a 100g sample, you need to know the molar mass of carbon. The molar mass of carbon is 12 g/mol. Therefore, in a 100g sample, there would be 100g / 12 g/mol = 8.33 moles of carbon.
How many moles are in a gram of carbon?
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
If i have 6g carbon how many moles is this?
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
How many moles of oxygen atoms are there in 100.0 moles of carbon dioxide?
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.
How many moles are in 56 grams of carbon monoxide?
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
Which has more atoms 10 moles of carbon or 10 moles of calcium?
10 moles of calcium has more atoms than 10 moles of carbon, as calcium has a higher atomic number and atomic weight compared to carbon. Each mole contains Avogadro's number of atoms, so the element with the larger atomic weight will have more atoms in 10 moles.
How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?
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.
How many moles of carbon are in 0.100 moles of carbon dioxide?
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
How many moles of carbon are in 2moles of sugar?
There are 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 88.1 moles of water vapor?
The balanced chemical equation for the reaction is 2H2 + CO2 -> 2H2O. This means that 2 moles of hydrogen gas react with 1 mole of carbon dioxide to produce 2 moles of water vapor. Therefore, to produce 88.1 moles of water vapor, 44.05 moles of hydrogen gas would be needed.
How many moles of CO2 molecules are present in 11g of carbon dioxide?
molecular weight of carbon dioxide = 44u gram molecular weight of carbon dioxide = 44g given mass = 11g no. of moles = given mass divided by molar mass = 11 divided by 44 = 0.25moles.
How many moles of carbon are in a diamond weighing 1200 grams?
Diamonds are all carbon. just divide 1200 grams by 12.01 grams per mole carbon.
How many moles of carbon are present in a 100g sample?
To calculate the number of moles of carbon in a 100g sample, you need to know the molar mass of carbon. The molar mass of carbon is 12 g/mol. Therefore, in a 100g sample, there would be 100g / 12 g/mol = 8.33 moles of carbon.
