C3 Quantitative Chemistry Flashcards
What is relative formula mass?
Total relative atomic masses in a compound.
what is conservation of mass?
total mass of reactants = total mass of products.
What is the equation for moles?
Moles = mass / relative atomic/formula mass
How many cm3 are there in 1dm3?
1000cm3 = 1dm3
What is percentage yield?
What mass of product is made in a reaction in reality, compared to the maximum theoretical mass that could be made.
What is the equation for percentage yield?
total mass of products / total mass of reactants x 100
What is atom economy?
Tells you how much of a desired product can be made in a reaction compared to the total mass of reactants.
What is the equation for atom economy?
RAM of desired product / total RAM of reactants x 100
What is gas volume?
1 mole of any gas takes up a volume of 24dm3 (this is true for room temp and pressure)
