Hello students, here in this question we have given these information.
00:03
Here we have to find out the gram of helium.
00:06
So, first we have to calculate the number of moles.
00:09
So, pv is equals to nrt.
00:13
From here we can find the number of moles.
00:16
So, n is equals to pv by rt.
00:22
So, p is the pressure that is 84 atm and the volume is given that is 0 .35 liter and the gas constant that is 0 .082 liter atm, mole inverse, kelvin inverse, the temperature is 306 kelvin.
00:48
From here we can cancel out the kelvin one and liter atm with this one and we'll get the number of moles that is equals to when we putting the values and we get...
