Question

Consider the compound Sn(CO3)2 and answer the following questions.

What is the name of this compound?
What is the molar mass of this compound? Explain how you calculated this value

THIS IS MY LAST QUESTION ON MY 45 QUESTION EXAM CAN SOME ONE PLEASE HELP..

Answer 1

Sn = Tin
CO3 = Carbonate
Since it's (CO3)2 , tin is of a charge of 2+
So, Sn(CO3)2 = Tin (II) carbonate

From the periodic table
Sn = 118.7
C = 12.0
O = 16.0

Molar mass of Sn(CO3)2 = 118.7 + ( 12.0 + 16.0 x 3 ) x 2
= ... ?
