Question

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

Answer 1

The answer to your question is 0.3 moles of NaCl

Step-by-step 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
