Hello Professor Pounds,
<div><br>
</div>
<div>In your solution to number 58 in Chapter 10 of Burdge, I'm
curious on what the purpose of finding the Molar mass of the
unknown compound would be? Is F2P the molecular formula of the
compound?</div>
<div>Thank you!</div>

is the empirical formula. The problem asks for the molecular
formula. The molar mass lets me determine how many units of the
empirical formula are necessary to make up the molecular formula.
In this case the molecular formula would be <img
