They are students, phosphorus reacts with chlorine to form phosphorus trichloride.
00:04
11 .8 gram of phosphorus, when allowed to react with 44 .3 gram of chlorine, how much of phosphorus tri chloride will form? this is our question.
00:14
Since amount of both phosphorus and chlorine are given, so you have to first find out the limiting reactant and from the value of limiting reactant we will find out the amount of p .l3 formed.
00:28
So let us convert this into their mold.
00:30
Their masses into moles by dividing with their molar mass.
00:35
So molar mass of phosphorus is 124, therefore it is coming almost 0 .095 mole.
00:44
Now chlorine, chlorine is here 44 .3 divided by its molar mass is 71.
00:52
It is 0 .6 to 4 approximately.
00:58
So we got their moles.
00:59
Now we'll divide in their coefficients...
