Answer:

5.74 gm

Explanation:

First, use the ideal gas law   PV = n RT

  to find the number of moles, then multiply by 28 g/ mole

PV = n RT    T must be in Kelvin    R = 8.314463 L kPa/(K - Mol)

                         ( make sure you use the R with the correct units!!)

182 kPa * 3 L  =  n (8.314463 ) ( 273.15+47.2)

 solve for n = .205 moles

.205 mole * 28 g/mole = 5.74 gm
