The density told you the mass covered by one unit of volume of that substance.
Density defines how perfectly the molecules of a substance are packed in a unit of volume.
In the given problem the substances are expressed in g/ml which means that a unit of volume will be 1 mL.
Given ,
Density of mercury = 13.546 g/ml
It means 1mL of mercury will have a mass of 13.546 g, Similarly 1 mL of ethanol will have a mass of 0.789 g.
0.350 L * 10^3 ml/1 L* 13.546/1 mL = 4,741.1 g
The volume of ethanol will have an equal mass is
4741.1 g* 1 mL/0.789g = 6,008.9 mL
6,008.9 mL* 1L/10^3mL = 6.0081 L
Hence the answer is 6.0081 L

Explanation:
Given parameters:
Mass of water = 18.5g
Initial temperature of water = 35°C
Finial temperature = -5°C
Unknown:
Amount of heat given off = ?
Solution:
In converting the water to ice, the water goes through these processes:
35°C to freezing point at 0°C = mcΔT
0°C of water to 0°C of ice = mL
0°C of ice to -5°C = mcΔT
The heat given off;
H = mc₁ΔT + mL + mc₂ΔT
m is the mass of water
c₁ is the specific heat capacity of water = 4.2J/g °C
c₂ is the specific heat capacity of ice = 2.03J/g °C
L is the latent heat of fusion = 334J/g
ΔT = T₂ - T₁ = temperature change
H = 18.5 x 4.2 + (0-(-35)) + (18.5 x 334) + (18.5 x 2.03 x (-5 - (0))
H = 2719.5J + 6179J + 187.8J = 9086.3J

That would be the NOBLE GASES (Helium, Neon, Argon, Krypton, Xenon, Radon). Because these elements have a filled outer shell (thus giving them the full octet that other elements crave), they are stable elements under normal circumstances and as such resist chemical combination.
Plz note that under special conditions, noble gases such as Xenon and Radon can form compounds (Xenon Fluoride and Oxide; Radon Fluoride)
