Hello student.
00:02
For the first part of the question we can write by the charles law that is v1 divided by t1 is equal to v2 divided by t2 when pressure is constant.
00:16
And here p means pressure, v1 means volume, t means the temperature.
00:21
So after putting the value, we will get v2 is equal to v1 multiplied by t2 divided by t2 divided.
00:31
By t1.
00:33
Now we are putting down the value.
00:35
So here it is 7 .4 multiplied by 312 kelvin that will be divided by 19 plus 273 kelvin.
00:47
So this will be equal to 7 .91 ml.
00:52
So this is our first answer.

Moving to the second part, we can say that according to the boil slope, t1, v1 is equal to p2 v2 when temperature is constant so here if we put down the value 3 .5 a tm multiplied by 2 .6 liter that is equal to 11 a tm multiplied by v2 or here v2 is equal to 0 .8 3 liter so this is the second answer for our question so this is liter moving to the third part here according to the boils and charge combined law we can write down p1 v1 divided by t1 is equal to p2 v2 divided by t2 so here we can if we put down the value 0 .7 a tm multiplied by 22 .0 liter that will be divided by 288 kelvin that is equal to 0 .250 multiplied by v2 and whole divided by 286 kelvin or here v2 is equal to 61 .17 liter.
02:06
So this is our third answer for this question.
02:11
Now moving to the fourth part according to the graham's law of diffusion, we can say r of f2 divided by r of br2 will be equal to whole root.
02:25
Over of molar mass of br2 divided by molar mass of f2.
02:33
So here if we put down the value, r of f2 we have to calculate and r of br2 is 2 .54 moles per second that will be root over of...
