Weight / Crucible Crucible A (g) Crucible B (g)

W0 65.4138 63.5762

W1 67.4185 65.5260

W2 65.5493 63.7105

where,

W0 = the weight of crucible

W1 = weight of crucible added with 2 gram of sample

W2 = weight of crucible added with 2 gram of sample after being put inside the fur-

nace

W2 - W0

To calculate ash content of the sample ( %) = —————- x 100 W1 - W0

For crucible A :

65.5493 - 65.4138

————————— x 100 % = 6.759 %

67.4185 - 65.4138

For crucible B :

63.7105 - 63.5762

————————— X 100 % = 6.866 %

65.5260 - 63.5702
