Question

What is the density (g/L) of 5.0 moles of NH3, at 1.18 atm and 25.0°C?

Answer 1

The answer will be 4667C

Answer 2

Answer:

.821 g/L

Explanation:

It does not matter what the gas is, just the number of moles to calculate volume....

Ideal Gas Law :  

PV = n R T       R = gas constant = .082057 L-atm/(mol-K)  &  T in Kelvin units

(1.18)(V) = 5 * .082057 * (25 + 273.15)

V = 103.67 Liters

NOW ...to calculate density, the gas  IS important...

  mole weight of NH3  (from periodic table) =  17.031 gm/mole

Density =  mass / volume    =    (5 * 17.031) / 103.67 L = .821 gm/L
