Chemistry Question... Very confused...?

Question

The ________ shows the quantity relationship between two species in a chemical reaction. We get this relationship from the _______.

a) molarity; stoichiometric coefficients

b) molar mass; balanced equation

c) atomic mass; balanced equation

d) molar concentration; balanced equation

e) mole ration; stoichiometric coefficients

______________________________________...

My guess is E but they all seem so similar...

Answer 1

E

molarity, molar mass, molar concentration are usually mols/quantity and does not realy show relationship between 2 species in a reaction

atomic mass does not have to do with relationship between 2 species in a reaction

mole ratio on the other hand is a ratio relating the species in a chemical reaction which is what you're looking for. The coefficents show the ratio (which you need a balanced equation for, but a balanced equation itself does not indicate anything, it is the coefficients that are indicative of the mole ratio.)
