We are told we have a mixture of p and cl2, and it forms p, c, l3, and p .l5.
00:25
Find the mass of pcl3.
00:34
I am not sure i can do this one.
00:59
Okay, maybe i can.
01:04
So i have p plus c02, and they're performing these two, or producing those two products, and i can balance it just like this, so i think i've got it here.
01:16
We'll see.
01:19
We're given 22 .0 grams of p and we're given 80 .0 grams of cl2.
01:30
We're asked to find the mass of plc that forms.
01:44
So we're asked to find the mass of that substance that's produced.
01:52
Let us begin our calculations.
01:57
So chlorine is 70 .91 and phosphorus, this is 30 .97, i think.
02:11
Yes.
02:33
Then i need next, my molar mass of p -c -l -3.
02:40
That will be 137 .33.
02:57
Let me do this math.
02:58
22 times 137 .33 divide 30 .97 .97 .97 .97 .97 .97 .97 .97 .97 .97.
03:09
97.
03:09
97...
