Hello students, let's discuss the question here.
00:02
In this question, for each of the part, few of the values are given and we have to find out the unknown.
00:10
In this case, one equation will be used, that is ideal gas equation, pressure, multiplied by volume, is equal to number of mole multiplied by gas constant, multiplied by temperature.
00:24
The value of gas constant, this is 0 .0 .0.
00:30
A21 and unit of gas constant, this is 18, that is atmospheric pressure multiplied by liter, divided by mole, divided by kelvin.
00:47
Here, as we can see that pressure, this is given in thor, but we need this in atmospheric pressure.
00:55
For that, we need to divide this by 760.
01:05
This will be equal to 8 .789 atmospheric pressure.
01:12
Here temperature is given in degree celsius, but we need this value in kelvin, that is, this will be equal to 27 plus 27.
01:22
That is, this is equal to 300 kelvin.
01:27
Hence the number of moles of nitrogen gas in this case this will be equal to pressure that is 8 .789 multiplied by volume that is 347 multiplied by 10 x to power minus 3 because we will convert milliliter into liter divided by rate constant that is 0 .0821 1 multiplied by 300 that is temperature when we will solve this value this will be equal to 0 .124 mole next we will move to the second situation here temperature pressure and mass of hydrogen gas is given from mass we will find out the number of moles in this case that is this will be equal to mass divided by molecular mass, molecular mass of h2, this is 2.
02:34
This is equal to 227 moles.
02:39
Here, in this question, volume needs to be calculated.
02:44
Volume, this will be equal to number of moles, that is, 227, multiplied by gas constant, 0 .0821 multiplied by temperature...
