Answer
$602g$ of epsom salts $(MgSO_4)$.
Work Step by Step
1. Determine the molar mass of this compound $(MgSO_4)$:
$Mg: 24.31g +$
$S: 32.07g +$
$O: 16.00g * 4= 64.00g$
= 120.38g/mol
2. Calculate the mass, using the molar mass as a conversion factor
$ 5.00 mole \times \frac{ 120.38g}{1mole} = 602 g$
