Hello, my name is john, and there are two parts of this question, and we have to find the number of molecules in each of the following gases at stp.
00:08
So for letter a, we have 0 .150 grams of carbon monoxide, where for every one mole of co, it weighs approximately 28 .01 grams, which comes out to be approximately 5 .36 times 10 to the negative 3rd moles of co.
00:28
Now, for every this amount of moles, we're going to use avogadro's number to find the number of molecules present, where one mole of co is equal to 6 .022 times 10 to the 23rd molecules of co.
00:48
Once we plug this into our calculator, we find the amount of molecules of co or carbon monoxide to be approximately 3 .22 times 10 to the 21st molecules of.

Of carbon monoxide.

Now for part b, we have 100 mil liters of hydrogen or h2...
