Consider an ideal gas enclosed in a 1.00 l container at an internal pressure of 18.0 atm. calculate the work, w , if the gas expands against a constant external pressure of 1.00 atm to a final volume of 18.0 l.

(1.6 × 10-19)(5.0 × 106) = c × 10d identify the missing numbers below to show the result of multiplying the numbers.
