The name of $Mn_2(SO_4)_3$ is : "Manganese (III) sulfate".
1. Identify the positive ion, and name it. $Mn^{3+}$ is the positive ion. So, the first name of the compound will be: "Manganese (III)"; 2. Identify the negative ion, and name it. $S{O_4}^{2-}$ is the negative ion. As we can see in Table 2.2 (Page 58), this ion is called "sulfate". 3. Putting those two names together: Manganese (III) sulfate.
