Answer:

0.119 moles

Explanation:

Mass measured by Nurse Antonio is 7 grams of NaCl

To find,

The no of moles of NaCl

The number of moles is given by

n=\dfrac{m}{M}

m is given mass

M is molar mass

For NaCl, molar mass is 23+35.5 = 58.5 grams

So,

n=\dfrac{7}{58.5}\\\\n=0.119\ \text{moles}

Therefore, there are 0.119 moles of NaCl.
