Calculate the mass of SbI
3
formed when 1.20 g of Sb react with 2.40 g of I
2
, according to the equation,
2Sb
(s)
+ 3I
2(s)
---> 2SbI
3(s)
Solution:
To begin this problem we need to build the table.
In this table I decided to start with Sb. If you started with I
2
your
table will look like;
(mol reactant Sb
)
o
(mol reactant I
2
)
required
(mol reactant I
2
)
o
Conclusion
Now complete the table. When you have the calculations complete
check what I calculated
.
