How many grams of oxygen are needed to?
32 grams
1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.
How many moles of oxygen are reacted with moles of octane?
Clearly, 6 moles of octane reacts with 50 moles of oxygen. This assumes that octane is completely combusted.
Does octane react with oxygen?
Problem: Liquid octane reacts with oxygen gas to form carbon dioxide gas and water vapor.
How many grams of oxygen are in gas?
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
How many grams are in 18 moles of O2?
576 grams
Looking back at the formula n=m÷M , to find m, we need to make the formula look: m = n × M. The mass of O2 is [18 moles × 32 g/mol] = 576 grams. Overall, 12 moles of NaClO3 will produce 576 grams of O2.
How many moles of octane are in 14.0 g of octane?
Now the equation is balanced so convert 14 grams of octane to moles, 14grams/114 grams/mole, and you have 0.8421 moles of octane. 0.8421 moles octane x 25 moles O2/2 moles octane(from the balanced equation) =10.52 moles O2=10.52 moles x 32 grams O2/mole=336.84 grams O2.
What type of reaction is octane oxygen?
combustion reaction
Whenever we complete a combustion reaction a hydrocarbon (compound of C and H) there are generally the same products formed: CO2 and H2O. The fuel you burn in your car’s engine contains octane, C8H18. When octane is burned, the products are CO2 and H2O. The key ingredient to the process is the availability of oxygen.
How many grams of oxygen gas contains the same number of molecules as 16 gram of so2?
8 g
∴ 8 g of oxygen gas contain the same number of molecules as 16grams of sulphur dioxide gas.
How many grams of oxygen gas contains the same number of molecules as 16 gram of sulphur dioxide?
1/4 mole of sulphur dioxide will have the same number of molecules as 1/4 moles of oxygen. Therefore, 8 gm of oxygen gas contains the same number of molecules as 16 gm of sulphur dioxide gas.
