Question

Convert 5.4g of NaCl to moles

Answer 1

Answer:

.0924 moles of NaCl

Explanation:

So you know you have 5.4 g of NaCl and you need to know how many moles there are in this amount of NaCl

1. You'll need to find the atomic mass of the compound NaCl to help you solve for moles

• Sodium (Na) on the periodic table has a mass of 22.99

• Chlorine (Cl) on the periodic table has a mass of 35.45

Add these two together----> 22.99 + 35.45 = 58.44

Now you can calculate for moles

Written-out method:

5.4 grams of NaCl  |   1 mole of  NaCl              

                                | 58.44 grams NaCl                = .0924 moles of NaCl

Plug into calculator method:

(5.4 g of NaCl/ 58.44g NaCl= .0925 moles)
