Calculate the mass of 0.6 mol of MgO.

To calculate the mass of 0.6 mol of MgO, we first need to determine the molar mass of MgO.

The molar mass of MgO is the sum of the atomic masses of magnesium (Mg) and oxygen (O). The atomic mass of Mg is 24.305 g/mol and the atomic mass of O is 16.00 g/mol.

MgO = Mg + O
MgO = 24.305 g/mol + 16.00 g/mol
MgO = 40.305 g/mol

Now, we can calculate the mass of 0.6 mol of MgO:

Mass = moles x molar mass
Mass = 0.6 mol x 40.305 g/mol
Mass = 24.183 g

Therefore, the mass of 0.6 mol of MgO is 24.183 grams.

The molar mass of MgO is 40.30 g/mol. This means that 1 mole of MgO weighs 40.30 grams.

To calculate the mass of 0.6 mol of MgO, we can use the following formula:

```
mass = moles × molar mass
```

Plugging in the values we have:

```
mass = 0.6 mol × 40.30 g/mol
mass = 24.18 g
```

Therefore, the mass of 0.6 mol of MgO is 24.18 grams.
