Question

Sodium chloride reacts with 0.10 moles of aluminum nitrate in water soultion. How many grams of sodium chloride are required?

Answer 1

Answer:

The answer to your question is 0.3 moles of NaCl

Explanation:

Data

NaCl = ?

Al(NO₃)₃ = 0.1 moles

Balanced reaction

                         Al(NO₃)₃  + 3NaCl    ⇒   3NaNO₃   +   AlCl₃

Now, use proportions to solve the problem

                       1 mol of Al(NO₃)₃  ------------ 3 moles of NaCl

                     0.1 moles of Al(NO₃)₃  --------  x

                          x = (0.1 x 3) / 1

                          x = 0.3 moles of NaCl
