Let's see here.
00:01
What is my reaction? let me write down the reaction we're given.
00:20
Okay, copper, copper two, two.
00:22
Okay, there's my reaction.
00:24
This is given.
00:28
Suppose you run the reaction yourself, you use one point, you use, it says you use 1 .5 -0 -0 grams of c -u -2o with excess h2 gas.
00:56
So this is limiting in the chemical formula.
00:59
Calculate the number of grams of cu expected in the reaction.
01:04
Okay, so let's try co2o plus h2 yield cu cu plus h2o.
01:18
So i think the only thing that'll change here is this.
01:29
And we're told how much of this we have.
01:33
Okay, so what i'm going to do.
01:35
Do is find my theoretical yield of cu and i have 1 .5 0 .00 grams of cu2o.
01:54
Let me get to my molar mass tab and find the molar mass of cu2o.
01:59
I think it's 143 .043.
02:14
Then i'm going to use my 1 to 2 mole ratio for copper to co2oo and finally my atomic mass of copper, which is 63 .55 grams per mole...
