The loss of mass on drying of the sample, expressed as a percentage by mass, is given by:

m1 — m2m1 — m0100 where:

×

m₀

mass, in g of the dish and its lid after process 5.2;

m₁

mass, in g of the dish, its lid and the test portion before drying (process 5.3);

m₂

mass, in g of the dish, its lid and the test portion after drying (process 5.4.3 or 5.4.4).

Calculate the loss on drying to the nearest 0,01 %.
