stoichiometric calculations?
butane, the principle ingredient of one kind of bottle gas, is commonly used as a fuel in campers and mobile homes. what mass of carbon dioxide would be produced, if 5.58g of butane were used to react with sufficient oxygen?
please show me the steps on how to do it for future question and not just the answer
OK, first of all you need to know the formula of butane: C4H10.
Then you need to know how it reacts with oxygen:
C4H10 + O2 --> CO2 + H2O
Every combustion reaction involves reacting a hydrocarbon with oxygen to get carbon dioxide and water (if you didn't know this already, you may want to memorize it).
Make sure your equation is balanced. After balancing we get:
C4H10 + 6.5O2 --> 4CO2 + 5H2O
If I wanted to, I could double the numbers in front of each molecule (to avoid having "fractions" of moles), but this is unnecessary, because all I really need to know is that for every mole of butane that reacts, we are going to end up with four moles of carbon dioxide.
So, let's begin the calculations:
First, find out how many moles of butane are in 5.58 grams. From it's molecular formula we learn that butane weighs 58 grams per mole (4*12+10*1). If we divide 5.58 grams by 58 g/mol we get: 0.0962 moles.
Second, we figure out how many moles of CO2 were produced. Because there is a 4:1 ratio of CO2 to butane, we multiply 0.0962 by 4, and we get: 0.3848 moles.
Finally, we calculate how many grams exist in 0.3848 moles of carbon dioxide. From it's molecular formula, we know that CO2 weighs 44 g/mol (1*12+2*16). So, if we multiply 0.3848 moles by 44 g/mol we end up with: 16.9 grams of carbon dioxide.
Ta-da!
