Answer:

m = 204.16 grams

Explanation:

Given that,

No. of moles, n = 3.49

Molar mass of NaCl, M = 58.5 g/mol

We need to find the mass of 3.49 moles NaCl​. We know that,

[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=3.49 \times 58.5\\\\m=204.16\ g[/tex]

So, there are 204.16 grams in 3.49 moles NaCl​.
