Can someone me convert 10.0 mols to a weight in mass?

See below

Explanation:

Let's say that you want to find the mass of 10.0 mol of MgSO₄.

The first step is to calculate the molar mass of MgSO₄:

1 Mg  =   24.30 g/mol

1 S     =   32.06

4 O   =   64.00          

Total = 120.37 g/mol

So, 1 mol has a mass of 120.37 g

Next ,you calculate the mass of 1.0 mol of MgSO₄

Mass of MgSO₄ = 10.0 mol MgSO₄ × (120.37 g MgSO₄/1 mol MgSO₄)

                          = 1200 g MgSO₄

                          = 1.20 kg MgSO₄

So, 10.0 mol of MgSO₄ have a mass of 1.20 kg.
