Upon decomposition, one sample of Magnesium Fluoride produced 1.65 kg of magnesium and 2.57 kg of fluorine. A second sample produces 1.33 kg of magnesium. How much fluorine (in grams) did the second sample produce?

Answer 1

......MgF2 ==> Mg + F2
..............1.65..2.57
Therefore, MgF2 must have started at 1.65 + 2.57 = 4.22 kg.

Second sample produced 1.33 kg Mg.
F2 produced = 2/57 x (1.33/1.65) = ? kg. Convert to grams.

Answer 2
