Upon decomposition, one sample of magnesium fluoride produced 1.55 kg of Magnesium and 2.42 kg of fluoride. A second sample produced 1.10kg of magnesium. How much fluoride (in grams) did the second sample produced?

Answer 1

Probably none. I'm sure you meant FLUORINE and not fluoride.
Just set up a proportion.
(1.55/1.10) = (2.42/x) and solve for x
