Question

How many moles of NaCl are

equivalent to 15.6 g NaCl?
(Na = 22.99 g/mol, Cl = 35.45 g/mol)

Answer 1

The answer is

0.267 moles

Step-by-step explanation:

To find the number of moles of NaCl we must first find it's molecular mass M after that we use the formula

`n = (m)/(M)`

where

n is the number of moles

m is the mass

M is the molecular mass

From the question

m of NaCl = 15.6 g

M( NaCl ) = 22.99 + 35.45 = 58.44 g/mol

Substitute the values into the above formula and solve

That's

`n = (15.6)/(58.44) \\ = 0.266940`

We have the final answer as

0.267 moles
