Answer is 334.35 g.

<em>Explanation:</em>

n = m/M

Where n is the number of moles of given substance (mol), m is the mass (g) and M is the molar mass of the substance (g/mol).

n = 3.99 mol
m = ? 
M = 83.798 g/mol

By applying the formula,
    3.99 mol = m / <span>83.798 g/mol
</span>               m = 3.99 mol x <span>83.798 g/mol
</span>               m = 334.35 g
