How many moles of oxygen are needed for complete combustion of butane?

132 moles
Complete step by step answer: You can observe in the above reaction that, 132 moles of oxygen are required for combustion of 1 mole of butane.

What is the mole ratio of butane to oxygen?

Notice that you have a 2:13 mole ratio between butane and oxygen, which means that, regardless of how many moles of butane react, you’ll always going to need 13/2 times more moles of oxygen for the reaction to take place.

How many moles are in 2 oxygen?

per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

How many moles of oxygen are in 2 moles of CO2?

The formula of carbon dioxide is CO2. One molecule of CO2 contains one atom of carbon and two atoms of oxygen One mole of CO2 contains one mole of carbon atoms and two moles of oxygen atoms.

How many moles of oxygen are required for complete combustion of 1 mole propane?

5 moles
From the equation, 1 mole of propane will react with 5 moles of oxygen.

How many moles of oxygen are required to completely burn 2.5 moles of butane?

Butane burned in just enough oxygen yields carbon monoxide and water the balance formula therefore is 2 C4H10 + 9 02 —-> 8 CO + 10 H2O. So as you can see the balanced equation needs 9 moles of oxygen to complete the reaction.

What is the molar ratio?

Molar ratios can be derived from the coefficients of a balanced chemical equation. Stoichiometric coefficients of a balanced equation and molar ratios do not tell the actual amounts of reactants consumed and products formed.

How many atoms are in 2 moles oxygen?

There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .

How many moles are in 12g of CO2?

1 mol
12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

How many moles are present in 12g of carbon?

1 mole
This is the theoretical atomic mass of the Carbon-12 isotope (6 protons and 6 neutrons). This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
