Epsom salt is used in tanning leather and in medicine. It is hydrated magnesium sulfate, MgSO4 7 H2O. The water of hydration is lost on heating, with the number lost depending on the temperature. Suppose you heat a 1.394-g sample at 100 C and obtain 0.885 g of a partially hydrated sample, MgSO4 x H2O. What is the value of x?

I need help with this question that is attached. Table 1.4 gave the ionic radii in pm. For k+ it was 138(6), 151(8),159(10) and for f- it was 128(2), 132(4), 133(6). Table 1. 5 gave ionization energies in kj/mol. For k they were 419, 3051 and 4410. For f it was 1681,3375, and 6050. Table 1.6 gave electron affinities in kj/mol and for k it was 48 and for f it was 328. I've also attached the resource table
Hypothetical elements X and Y form a molecule XY2, in which both Y atoms are bonded to atom X (and not to one another). The X—X distance in the elemental form of X is 204 pm, and the Y—Y distance in elemental Y is 168 pm. What would you predict for the X—Y distance in the XY2 molecule? Explain your answer.
