##### 1 Answer

The density of your argon sample will be **18.9 g/L**.

So, you know that you have a sample of argon under certain conditions of temperature and pressure. In addition to this, you know the volume the sample occupies.

THis means that you can use the ideal gas law equation to determine how many moles of gas your sample contains.

Now use argon's molar mass to determine the mass of your sample

Since density is defined as mass per unit volume, you've got all you need to calculate it

Rounded to three sig figs, the answer will be
