determine how many equivalents of each ion are present. round each of your answers to 2 significant figures…

Explanation:

Step1: Recall equivalence formula

The number of equivalents (Eq) of an ion is calculated as the number of moles (mol) times the charge of the ion. For a monovalent ion like $K^{+}$, the charge is 1. For a divalent ion like $S^{2 - }$, the charge is 2.

Step2: Calculate equivalents of $K^{+}$

For $1.5\ mol\ K^{+}$, since the charge of $K^{+}$ is 1, the number of equivalents is $n = 1.5\ mol\times1=1.5\ Eq$. Rounding to 2 significant - figures, it is $1.5\ Eq$.

Step3: Calculate equivalents of $S^{2 - }$

For $2.2\ mol\ S^{2 - }$, since the charge of $S^{2 - }$ is 2, the number of equivalents is $n = 2.2\ mol\times2 = 4.4\ Eq$.

Answer:

Part 1 of 2: $1.5\ Eq\ K^{+}$ Part 2 of 2: $4.4\ Eq\ S^{2 - }$
