0.164 g/L is the density of a sample of 1.00 mole of at 793mmhg and -9.00 degrees celcius.
<h3>What is density?</h3>
Density is the mass of a unit volume of a material substance. The formula for density is d = , where d is density, M is mass, and V is volume.
Given data:
n = 1.00 mole
P=793 mm hg =1.04342 atm
T=-9.00 degree celcius = -9.00 + 273= 264 K
V=?
Using Ideal Gas Law equation:
PV = n R T
R = gas constant = 0.082057 L-atm/(mol-K)
(1.04342 atm)(V) = 5 X 0.082057 L-atm/(mol-K) X 264 K
V = 103.67 Liters
Now calculate density:
Mole weight of = 1.00 mole
So, the mass of = 17.031 g
Density =
Density =
= 0.164 g/L
Hence, 0.164 g/L is the density of a sample of 1.00 mole of at 793mmhg and -9.00 degrees celcius.

Answer: The value of the equilibrium constant is 0.00009.
Explanation:
Initial moles of = 0.15 mole
Volume of container = 10 L
Initial concentration of
Moles of at equilibrium= 0.03 mole
equilibrium concentration of [/tex]
The given balanced equilibrium reaction is,
Initial conc. 0.015 M 0 0
At eqm. conc. (0.015-2x) M (2x) M (x) M
The expression for equilibrium constant for this reaction will be,
we are given : 2x= 0.003 M
x= 0.0015 M
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is 0.00009.
