# Stoichiometry Problem Solving

You can find the right amount to optimize the reaction and save reactants so you don't waste money. To help you understand how astronomically big this number is if I gave everyone on Earth (estimated 7 billion) million dollars a day; I could keep handing out money for 78564 years. For solids or liquids that aren't solutions its sample mass/molecular weight=moles. For example to find one mole of lets say carbon-14 the equation is x/14=1 x=14grams Another example: Find 5 moles of H2O. First off just pick a molecule(any of them work but the biggest is usually the best) and assign it a number (again any number works but to keep it easy use one).So far we have: C6H12O6 O2 -- H2O CO2 (1) So on the left side we have 6 carbon atoms 12 hydrogen atoms and an unknown amounts of oxygen atoms. Since we know the left sides number of carbon and hydrogen atoms we know the right sides number.

Gas changes volume depending on temperature, and pressure. V- volume T- temperature k- constant Charles's law must be done in Kelvin because it is an direct variation.

If you add up the mass for one side it should equal the sum of the mass on the other side.

If not you messed up somewhere and need to review your work.

In simple words it states as pressure increases so does temperature. P- pressure T- temperature k- constant You can combine all three of those laws to get the combine gas law. To use this with stoichiometry you need to combine it with one last law, which is Avogadro's law.

It states that at constant temperature and pressure equal volumes of gas contain the same number of moles.
