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.

You can separate a mixture of salt and sand by...
First combing the mixture with water and mix thoroughly until the salt dissolves..
Then you could let the sand settle at the bottom of the salt water, so you can strain salt water to separate the sand from salt water...
To get salt... you would heat up the water to let it evaporate. When all the water is evaporated, the salt will be left behind
Algae is not an abiotic factor.

Equate the gravitational force to the electrostatic force:
<span>KC²/D² = Gm²/D² → C = m√[G/K] = 7.6√[6.67E-11/9E9] = 6.54E-10 coulombs </span>
<span>Number of electrons N = 6.24E18*C = 4.083E9 electrons</span>
