Question

What is the density of ammonia gas at 2.00 atm pressure and temperature of 25.0 C

Answer 1

Explanation:

1.39 g/L 16.6 g/L 0.720 8/L 0.980 B/L.

Answer 2

In chemistry, the density of a material is an intensive property which is defined as the material's mass per unit of volume:

$\rho =\frac{mass}{volume }$

The more dense the material is, the higher mass the material occupies for a given volume. The SI unit for density is $\frac{kg}{m^3}$.

The molar mass of ammonia is 17.031 g/mol. The number of moles can also be written as $n=\frac{m}{MM}$ where m is the mass of the gass and MM is the molar mass of the gas. The density is computed by isolating the $\frac{m}{v}$in the ideal gas equation as shown below:

$PV=nRT$

$PV=\frac{m}{MM}\times RT$

Density $=\frac{m}{v}=\frac{MMP}{RT}$

Density $=\frac{(17.031 \frac{g}{mol}(2.00atm) )}{0.0821 \frac{L atm}{mol K} (25+273.15k) } =1.39\frac{g}{L}$
