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

The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (v).
vovangra [49]

Answer:

Density is an intensive property

Explanation:

The intensive properties don´t depend on mass or size, if you have a liter of water, this litter have a density equal 1000 kg/m^3. If zo have 250 liters of water, the density is 1000 kg/m^3 too.

The density does not change with the addition or substraction of matter.

I hope I have been clear.
