Loss of Mass Method
What is Loss of Mass Method?
A practical technique for following a reaction rate in which the reaction vessel stands on a balance and its mass is recorded at regular time intervals. It works only when a product leaves the apparatus, almost always as a gas, so that the falling mass measures the amount of product formed.
