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.
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 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 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 nitrogen and oxygen are in a cubic foot?
Molecules or moles? And in a cubic foot of what? Air?
How Many Moles of air are there in a 3 L container of 1 ATM pressure and 293?
0.125 moles
An adult human lung has a volume of 2.9 liters. If its volume decreases to 1.2 liters and it contains 0.049 mole of air after it exhales, how many moles of air does it contain when full A. 0.025 mol B. 0.041 mol C. 0.083 mol D. 0.12 mol E. 0.14 mol?
