Upon decomposition, one sample of magnesium fluoride produced 1.65 kg of magnesium and 2.57 kg of fluorine. a second sample produced 1.32 kg of magnesium. how much fluorine (in grams) did the second sample produce?

Respuesta :

The ratio of mass of magnesium to fluorine will always be the same. 
so we have  1.65 / 2.57 = 1.32 / x

x =  2.57 * 1.32  /   1.65  =  2.056 kg Answer
