Taking the compound with the metallic counterpart of highest mass would be the answer. Looking at the periodic table, it is easy to realize that K has the highest mass out of H, Li, K, and Cl. Therefore, the answer is (2) KCl.
Answer:
15 g/mol
Explanation:
If you need to round 14.8232 g/mol down to 2 significant figures, you start on the left, count in two (14) and round with the next number (.8).
Because 8 is higher than 4, you round up, getting the answer 15.
H2O because there are 2 H and only 1 O :)
