How many moles of water are produced when1 mol of butane reacts with excess oxygen?
Moles of butane = 9.33⋅g58.12⋅g⋅mol−1 = 0.161⋅mol . We assume complete combustion, and know that each mole of butane gives off 5 mol of water upon combustion.
What happens when butane is burned in excess of oxygen?
The chemical formula of butane is C4H10 . The combustion of butane is a reaction between butane and oxygen gas that produces carbon dioxide gas and water.
What are the products of butane burning in excess oxygen?
The combustion of butane in oxygen produces carbon dioxide and water. C4H10 + O2 → CO2 + H2O .
How many moles are in butane?
Experimental molar mass (g/mole) of butane: 0.23 g/0.0040 moles = 58 g/mole 13. The molecular formula of butane is C4H10. Calculate its molar mass.
What does it mean when something is burned in excess oxygen?
combustion
Another common example of combustion is the burning of wood to produce thermal energy. When 1 mole of propane (C3H8) is burned in excess oxygen, 3 moles of CO2 and 4 moles of H2O are produced. CombustionEnergy is released in the form of flames as the fuel combusts.
What is the heat of combustion of butane?
2877.5 kJ/mol

How many moles are in one gram of butane?
Experimental molar mass (g/mole) of butane: 0.23 g/0.0040 moles = 58 g/mole 13. The molecular formula of butane is C4H10.
How much water does a mole of butane produce?
Moles of butane = 9.33 ⋅ g 58.12 ⋅ g ⋅ mol−1 = 0.161 ⋅ mol. We assume complete combustion, and know that each mole of butane gives off 5 mol of water upon combustion.
How to calculate the atomic mass of water?
Calculate the maximum mass of water that can be made from an excess of carbon dioxide and 95.6 g of lithium hydroxide. (Relative atomic masses: H = 1.0, Li = 6.9, O = 16.0)
How to calculate the mass of a product?
A theoretical yield is the maximum possible mass of a product that can be made in a chemical reaction. Calculate the maximum mass of carbon dioxide that can be made from 6.0 g of carbon and an excess of oxygen.
How to calculate the atomic mass of ammonia?
Calculate the maximum mass of ammonia that can be made from an excess of nitrogen and 12.0 g of hydrogen. (Relative atomic masses: H = 1.0, N = 14.0)
