Calculate the mass of SbI3 formed when 1.20 g of Sb react with 2.40 g of I2, according to the equation,

2Sb(s) + 3I2(s) ---> 2SbI3(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 I2 your table will look like;

(mol reactant Sb)o

(mol reactant I2)required

(mol reactant I2)o

Conclusion

 

 

 

 

Now complete the table. When you have the calculations complete check what I calculated.
