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
