Now we will discuss a method to remove carbon dioxide from aircraft by using naoh.
00:07
Carbon dioxide when it is treated with naoh, it gives rise to sodium carbonate and water.
00:15
Here in the question they are asking how much co2 can be removed by using 1 kj of naoh? by seeing this stochometric equation, we know that 2 moles of naoh can remove 1 mole of co2, 2 moles of naoh can demu, 1 mole of co2.
00:41
In the question they are asking that 1 kg or 1 ,000 grams of naoh can demo how much of carbon dioxide.
00:49
And 2 moles of naoh we can also write it as 80 grams because it is its molecular mass.
00:57
80 grams can remove 1 mole.
01:00
In a question asking, 1000 grams can remove how much carbon dioxide? by using unitary method, we can solve this 1 ,000 grams into 1 mole divided by 80 grams.
01:19
Grams, grams will cancel out.
01:21
We'll get 12 .5 moles.
01:27
And they are also asking what is the pressure exerted by this moles of carbon dioxide.
01:34
This can be done by using the ideal gas equation pv is equal to n r -t.
01:44
By using ideal gas equation and volume is given as 310 liters, temperature is given as 25 degrees centigrade...
