A sample of a hydrated salt weighing 1.167 g is heated until no more water is given off. The mass of the anhydrous salt was 0.6298 a) What is the mass of water lost by the sample?

The mass of water lost is:

(2) = 1 − 2 = 1.167 − 0.629 = 0.538

The mass % of water in the hydrated salt is:

(2) =

(2)

1

=

0.538

1.167 ∙ 100% = 46.0 %

0.538 g; 46.0 %

explanation:

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
