Can someone please help with this I need the answers for the three boxes

Type: M

Name: Dixytrogen Pentasulfide

Molar Mass:

X*2 = Number * 2 = Number

S*5=32.066*5=160.33

Number + 160.33 = Molar Mass (g/mol).

(The mass for Xytrogen is not present).

Explanation:

Assuming Xytrogen is a non-metal and bonding it with sulfur, another non-metal would make it covalent or molecular.  

The name is from the amount of Xs (being two [Di]) and the amount of Ss (being five [Penta]).

The molar mass is explained above.  You need to multiply the mass of each element by the number of elements present in the compound.  The mass for Xytrogen is not present (as it is a made up element) so I left instructions how to do it once given the mass instruction.

Hope this helps.
