Hello students welcome here in this question a reaction is given so iodine is reacting with fluorine to give if2 more this is n and this one is also n so we don't know what is this n we have to calculate so and another two parts are there we will calculate and we will see what happens so here it is iodine we know that mass of this one is one is one 127 is the iodine mass.
00:33
So it is multiplied by 2.
00:36
So mass of iodine, 254 grams.
00:40
And here, n multiplied by 19 means 19 to is a 38.
00:46
Okay? so 38 is a mass of this one.
00:51
And now what is a mass of this one is iodine 127 multiplied by plus.
00:59
So this one is plus 19 plus 19.
01:07
Okay.
01:08
So this is our actual masses we are using in the reaction.
01:13
So they are given 100 grams of iodine is using.
01:18
So how this one is forming 144 .9 grams.
01:24
Okay.
01:25
So if you use this much of mass, you are getting this one.
01:29
Okay, so from this n we will calculate.
01:33
So from this one, 144 .9 multiplied by 254 is equal to 2 .4 plus 19 to 3038n.
01:51
Okay, so now n is equal to 3.
01:56
We will get after solving this one...
