Question

From the following balanced equation, 2 NaCl(s) 2 Na(s) + CL (8) - how many moles of NaCl can be formed from 3 mol Cl,? • Your answer should have one significant figure.

Answer 1

Step 1: Explanation:

A mole ratio is ​the ratio between the amounts in moles of any two compounds involved in a chemical reaction. The mole ratio can be determined by examining the coefficients in front of formulas in a balanced chemical equation.

Step 2: write the balanced chemical equation.

2Na(s) + Cl₂(g)---> 2NaCl(s)

Step 3: Calculate the moles of NaCl

2Na(s) + Cl₂(g)---> 2NaCl(s)

According to the reaction:
1 mol of Cl₂ produce 2 mol of NaCl
so, 3 mol of Cl₂ will produce=( 2 mol of NaCl / 1 mol of Cl₂ )×3 mol of Cl₂ = 6 mol of NaCl

Hence, Moles of NaCl can be formed = 6 mol
