Hello, so in this question we need to calculate the boiling point of the given solution.
00:08
So first i will find the change in temperature or we can say change in boiling point that will be calculated using the equation i which is the vent of coefficient b which is molarity times kb which is ibuloscopic constant.
00:27
Okay, this is ibuposcopic constant.
00:38
This is molality and this is vent of coefficient.
00:54
So using this equation, we will calculate the boiling point of solution.
01:00
So first step is we will calculate moles of iodine.
01:05
So, moles of iodine will be moles of iodine will be equal to molar mass of iodine given mass of iodine divided by molar mass.
01:20
Okay? so given mass of iodine is 9 .04 grams divided by molar mass is 253 .8 grams per mole.
01:33
So moles comes out as 0 .0356 moles.
01:39
Okay.
01:39
So moles we have calculated.
01:40
For iod now we will calculate the molarity the molarity is equal to moles molarity will be equal to moles of iod divided by mass of solvent that is benzene in this case in kgs so moles of iodine is 0 .0356 divided by mass of benzene is given as 0 .0755 kilograms terms...
