Question

if you want to produce 6.2 moles nacl, how many moles of na will you need if you have excess cl2

Answer 1

Answer:

6.2moles of Na are needed.

Explanation:

First, we need to generate a balanced equation for the reaction between sodium and chlorine to produce sodium chloride. This is illustrated below:

2Na + Cl2 —> 2NaCl

From the equation,

2moles of Na produced 2moles of NaCl.

Therefore Xmol of Na will produce 6.2moles of NaCl i.e

Xmol of NaCl = (2 x 6.2)/2 = 6.2moles

Therefore, 6.2moles of Na are needed to produce 6.2moles of NaCl
