The compound Sn(CO3)2 is caled Tin(IV) Carbonate. And the molar mass can be calculated by the summation of the molecular mass of each element int he compound multiplied by the number of atoms there are. 

Sn 188.71 * 1
C          12 * 2
O            16*6
molar mass: 
238.7278 g/mol <---- answer

Answer:

The name of the given compound is tin carbonate and the molar mass of the given compound is 238.73 g/mol.

Explanation:

The nomenclature of ionic compounds is given by:

1. Positive is written first.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

3. If the negative ion is made up of more than one atom then write name of that particle polyatomic anion: carbonate for [tex]CO_3^{2-}[/tex], sulfate for [tex]SO_4^{2-}[/tex],phosphate for [tex]PO_4^{3-}[/tex] etc.

The name of [tex]Sn(CO_3)_2[/tex] : Tin carbonate

Atomic mass of tin = 118.71 g/mol

Atomic mass of carbon = 12.01 g/mol

Atomic mass of oxygen =  16.00 g/mol

Molar mass of tin carbonate = [tex]Sn(CO_3)_2[/tex]

= [tex]118.71 g/mol+2\times 12.01 g/mol+6\times 16.00 g/mol=238.73 g/mol[/tex]

The name of the given compound is tin carbonate and the molar mass of the given compound is 238.73 g/mol.
