Anything that includes numbers in it is quantitative . For eg if you take quantitive measure of weight of a body you would say its weight like 50gm or 10kg but qualitatively you would say that the body is heavy or light.
Quantitative describes actions or observations that utilize measurements or counting that can be analyzed and computed to arrive at a result.
A quantitative procedure means numbers will be used to compare or measure quantities of objects or substances used in the study of the reaction.
Quantitative analysis usually involves stoichiometry when instituted in a chemistry situation.
