1.25 pts An ionic compound has the formula Na XO4, where X represents an unknown transition metal. The compound has a molar mass of approximately 293.8 g/mol. Which of the following elements is the most likely identity of X?

Lead, Pb.

Explanation:

Hello!

In this case, since the molar mass of the compound is 293.8 g/mol, and the molecular formula is NaXO₄, we infer that the molar mass is computed via:

Thus, we can solve for the atomic mass of X as shown below:

Thus, the element whose atomic mass is about 206.8 g/mol is lead (207.2 g/mol) even when it is not properly a transition metal.

Best regards!

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

you need to have a picture of the atom that way we can answer it
