Okay, so let's answer now the question.
00:02
The nitrogen monoxide gas decomposes to form nitrogen gas and oxygen gas.
00:07
How many grams are formed with 10 grams of nitrogen monoxide decomposes? so we have here the balance equation.
00:16
Okay, 2 and 2 o plus, or it will result rather 2.
00:25
Okay, it will be decomposed to nitrogen gas and oxygen.
00:37
Gas.
00:39
So let's go to the answer.
00:40
So we know that the given mass for the dinitrogen monoxide is 10 grams, and the molar mass of dinitrogen oxide is, or di -dinitrogen monoxide, is 44 .013 grams per mole.
00:54
That's the molar mass of n2o.
00:56
Now, so number of moles of n2o, we have 10 grams divided by 44 .013 grams per mole, so we have 0 .20 0 .2272 mole.
01:13
So that's the mole of the n2o or the dye nitrogen monoxide.
01:21
So for us to solve what's the mass of n2, we will just multiply the 0 .2272 moles.
01:32
Okay 0 .27 okay wait let me erase this one 227 mole of the dinitrogen monoxide let's multiply that with 28 .0 or 28 grams per mole that's the molar mass of nitrogen gas and the answer is we have what's our answer the answer the answer is we have 6 .36 grams of 6.
02:19
So here's our first answer...
