#### Explanation:

We shall assume that this is an **Ideal Gas**, and can thus use the **Ideal Gas Law**:

where **Pressure** (pascals)

where **Volume** (

where **moles** (mol)

where **Temperature** (Kelvin)

and

Now, we convert the units:

Inputting the values into the equation:

Solve for n:

Thus, solved.
