When propane undergoes complete combustion in air for each mole of propane burnt how many moles of oxygen are consumed and how many moles of water are formed?
The answer is: 5 moles oxygen and 4 moles H2O.The reaction is:C3H8 + 5 O2 = 3 CO2 + 4 H2O
In order to get 1 mole of ammonia how many moles of nitrogen is needed?
Each mole of ammonia requires one mole of nitrogen atoms. However, the nitrogen in the air occurs as diatomic molecules; therefore, only one-half mole of molecular nitrogen is required for each mole of ammonia.
What is the mole fraction of oxygen gas in air?
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
A container with a volume of 564 L holds how many moles of air at STP?
1 mole of gas occupies 22.4 liters at STP. 564/22.4 = 25.18 moles (2 decimal places)
How many moles are there in 67.2 liters of carbon dioxide at STP?
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)
How many moles of oxygen are present in the air?
The amount of oxygen in the air is about 0.21 moles per liter.
How do moles get enough air to breathe?
Moles contain twice as much blood and twice as much red haemoglobin as other mammals of similar size, allowing the mole to breathe easily in its underground
How do moles breath?
Through their nose. Most moles have highly adapted noses that filter out dirt particles well. Mole holes usually have an end where air comes in. Moles, in fact, can be buried alive if their holes collapse.
What is the mole ratio of air to methane gas in the cumbustion of methane?
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
How many moles of nitrogen are there in 500 moles of clean dry air?
Clean dry air is composed of approximately 78% nitrogen by volume. Therefore, in 500 moles of clean dry air, the number of moles of nitrogen can be calculated as 0.78 x 500 moles, which equals 390 moles of nitrogen.
What is one mole of carbon dioxide?
Moles of what? Air (what you breathe) is not a consistent substance. It consists of nitrogen, oxygen and other things. If you mean moles of oxygen, we need to know the density. At 0*C, the density of oxygen is 1.429 g/L. We convert this to the volume we have and then divide it by the molar value of oxygen, 16 g/mol, to give us 4.47 x 10^4 mols.
How Many Moles of air are there in a 3 L container of 1 ATM pressure and 293?
0.125 moles
