In this question we are assigned with the task to fill in the empty blanks with the correct answer.
00:05
To fill in the blanks we should use the idle gas equation pv is equal to nrt.
00:11
For the first case we need to find the number of moles n.
00:15
Now let us look at the data provided by pressure is 6 atm volume is 2 .20 liters temperature is 45 .7 degrees celsius so in kelvin units it is equal to 318 .14.
00:32
So we can use the pv is equal to nrt formula to calculate n so n is equal to pv divided by rt by substituting all the known data.
00:45
It is 0 .5042 moles.
00:51
Now let us move on to the second case.
00:54
In this question we need to find the temperature in kelvin unit.
00:58
Pressure is 300 kilo pascal.
01:02
Now let us convert this to adium pressure.
01:04
So in pascal it is equal to 300 to 10 to the power.
01:08
3 pascals so to convert pascal to aetam we should divide this value by 101 300m it is 2 .9615 atm and volume is 4 ,500 mn so in litters it is equal to 4 .5 liters and number of moles n is 4 .04 now let us use the very same formula to calculate the temperature t so t is equal to pv by nr by substituting all known data is uncalculating, we find the value of tas.
01:42
It is 40 .1790 kelvin.
01:46
Now let us move on to the third case...
