Calculations Stoichiometry is crucial for understanding quantitative relationships in chemical reactions Stepbystep approach 1 Balance the equation Ensure the reaction is balanced with equal numbers of atoms on both sides 2 Convert given units to moles Use molar masses to convert masses of reactantsproducts to moles 3 Determine the mole ratio Identify the mole ratio between the substance youre given and the substance you want to find from the balanced equation 4 Calculate the desired quantity Use the mole ratio to find the moles of the desired substance then convert back to the desired units eg mass volume Example How many grams of oxygen are needed to completely burn 10 grams of methane CH Balanced equation CH 2O CO 2HO Calculate moles of CH 10g CH 1 mol CH1604 g CH 062 mol CH Mole ratio 2 mol O1 mol CH Calculate moles of O 062 mol CH 2 mol O1 mol CH 124 mol O Calculate mass of O 124 mol O 3200 g O1 mol O 3968 g O Common pitfall Forgetting to balance the equation first leads to inaccurate results II Delving into the Gas Laws Understanding Pressure Volume and Temperature Ideal gas law PV nRT is fundamental for understanding gases Key gas laws Boyles Law Charles Law Avogadros Law and their combination in the ideal gas law Stepbystep problemsolving Identify known variables use the appropriate formula and solve for the unknown Example A gas occupies 500 mL at 25C and 1 atm
