The Mole and Stoichiometry & Dimensional Analysis Flashcards
What is a mole?
A mole is a unit of measurement. It measures atoms, particles and molecules.
What is 1 mole?
6.022x10^23 particles
Explain the relationship in m=n*M.
Molar mass is the mass of 1 mole of a substance. The number of moles allows us to measure the amount of a substance that is present. Therefore, we multiply the number of moles by molar mass, so you can find the total mass of the substance.
The Conservation of Mass states…
the mass of reactants is equal to the mass of products in a chemical reaction.
What is stoichiometry?
It is the quantitative relationship between reactants and products in chemical reactions. It helps to determine the amounts of reactants needed or products formed in a reaction. It also helps to understand how different substances react with each other and how much is needed to react completely.
What is the factor label method?
It is also known as dimensional analysis, a problem-solving technique that converts units from one form to another.
