Answer:

m O2 = 116,16 g

Explanation:

Ca(ClO3)2 ------------> CaCl2 + 3O2

n Ca(ClO3)2 = 250/207 = 1,21 mol

n O2 = 3n Ca(ClO3)2 = 1,21 * 3 = 3,63 mol

m O2 = 3,63 * 32 = 116,16 g

A student was comparing the solubility of equal amounts of table salt and table sugar at different temperatures.The table below

Mama L [17]

The sample that has the highest solubility is THE FIRST SAMPLE [TABLE SUGAR NO 1].
Solubility refers to the quantity of a solute that will dissolve in a given volume of solvent at a given temperature and pressure. The question above tells us that equal amounts of sugar and table salts were used. But looking at the table given in the question, you will see that sample 1 has the highest amount of solute that dissolve, that is 80, the rest of the samples have values that are lower than that.
