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.

~Hello there!
Your question: Which produces the greatest number of ions when one mole dissolves in water?
Your answer: Na2SO4<span> can dissociate into three ions, whereas the other choices produce only two ions (or in the case of sucrose, none) when dissolved in water.
Any queries ^?
Happy Studying!

<h2>Ultraviolet Light</h2>
Explanation:
- The energy of a photon that will be released if an electron falls from the n= 2 orbit (excited state) to the n0 = 1 orbit (ground state) is of ultraviolet light.
- In the ultraviolet part of the spectrum, a photon having an energy of 10.2 eV has a wavelength of 1.21 x 10-7 m.
- Hence, when an electron wants to jump or it gets excited from the first level to the second level that is from n = 1 orbit to n = 2 orbits, it must absorb a photon of ultraviolet light.
- But,When an electron falls from n = 2 orbit to n = 1 orbit or from n = 2 orbit(excited state) to n = 0 orbit(groubd state), it emits a photon of ultraviolet light.
Inertia is the retaliation of an object to change in its velocity
