Solve for Pressure (Ideal Gas Law)?

Pxx0.21=2.1xx0.0821xx290P×0.21=2.1×0.0821×290

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

PV = nRTPV=nRT

P = (nRT)/VP=nRTV

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

= ???=???

What must the units of pressure become in this case?
