So for this problem, we're told that at stp, which is a temperature of zero degrees celsius or 273 kelvin and a pressure of one atm, we have one liter of bromine gas reacting completely with three liters of fluorine gas to produce two liters of a product.
00:20
And we're trying to figure out what is the formula of the product.
00:23
Now, according to avagadro's law, there is a relationship between, volume and moles.
00:32
So we can actually substitute the volumes in as coefficients to determine the molecular formula of our product.
00:38
So we know we have br2 plus f2, and it's going to produce some sort of product brx, f, y.
00:52
And we can substitute in our volumes.
00:56
So in this case, i was substitute in a 3 here for the f2 and a 2 here for the brf3 because we know that we have 3 liters of f2 and 2 liters of our product and one liter of the br so i don't have to write a coefficient there because of the fact that it is a 1...
