# Solve for Pressure (Ideal Gas Law)?

## $P \times 0.21 = 2.1 \times 0.0821 \times 290$ $P \times V = n \times R \times T$

You must put units on your equations... if you don't, it won't be clear what you have calculated...

$P V = n R T$

$P = \frac{n R T}{V}$

= (("2.1 mols ideal gas")("0.0821 L"cdot"atm/mol"cdot"K")("290 K"))/("0.21 L")

= ???

What must the units of pressure become in this case?
