<u>Answer:</u> The number of formula units in the given amount of NaCl are
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of NaCl = 0.11 mg = (Conversion factor: 1 g = 1000 mg)
Molar mass of NaCl = 58.5 g/mol
Putting values in above equation, we get:
According to mole concept:
1 mole of a compound contains number of formula units
So, moles of NaCl will contain = number of formula units
Hence, the number of formula units in the given amount of NaCl are
