Moles
Converting mass to moles in stoichiometry problems is necessary to determine the amount of reactants or products involved in a chemical reaction. This conversion allows you to compare the amounts of different substances based on their molar quantities rather than their masses, making it easier to balance equations and calculate the quantities of reactants needed or products produced.
The first step in most stoichiometry problems is to balance the chemical equation for the reaction you are studying. This ensures that you have the correct mole ratios of the reactants and products needed for further calculations.
To solve volume-to-volume problems in stoichiometry, you first need a balanced chemical equation. Convert the given volume of one substance to moles using the molarity provided (if applicable). Apply the stoichiometry ratios from the balanced equation to find the volume of the other substance in the reaction. Remember to convert between units as needed.
Here are some gas stoichiometry practice problems for you to work on: How many liters of oxygen gas are needed to completely react with 5.0 liters of hydrogen gas to produce water vapor? If 2.0 moles of methane gas react with excess oxygen gas, how many moles of carbon dioxide gas will be produced? A reaction produces 4.0 liters of nitrogen gas. If the reaction is 80 efficient, how many liters of nitrogen gas would be produced if the reaction was 100 efficient? These problems will help you practice applying gas stoichiometry concepts.
The first thing I do in any conversion question is identify the starting unit of measurement given in the problem and the target unit of measurement that needs to be converted to. This helps establish the conversion factor needed to solve the question accurately.

Multiply Km by 10^6
The conversion factor is 1,000 (km x 1,000 = meters)
Identify the quantities you have and the unit conversion factor needed. Set up a conversion factor with the units you want to convert to on top and the units you want to convert from on the bottom. Multiply the given quantity by the conversion factor to cancel out the unwanted units and obtain the desired units. Check that the units in your final answer are correct and make sense.
60 minutes = 1 hour Just divide the minutes by 60 to get hours
Assuming you are talking about stoichiometery a conversion factor is often a number with two units. For example a conversion factor could be Miles per hour (Miles/hour). If you had miles and needed to convert to hours you would multiply the miles by Hours/miles so that the miles would be canceled out (miles/miles = 1). Then your units left would be hours. Or vice versa. There are other factors like this in chemistry like grams/mol Mol/liter etc. To put it shortly the conversion factor denominator is always paired with the numerator.
