Answer:
Explanation:
Given that,
Initial volume, 
The pressure changes from 73.2 kPa to 122.5 k.Pa.
We need to find the new volume occupied by the air. Let it is V₂. It can be calculated using Boyle's law such that,
So, the new volume is 
.
Answer:
Ozone is a molecule with three oxygen molecules.It is in the upper atmosphere and it protects living organisms by keeping UV rays from reaching the earth's surface. Ozone (O3) is a triatomic, molecule, consisting of three oxygen atoms. ... O3 is the formula for ozone. It has three oxygen atoms.

Answer:
[Ag+] = [NO3-] = 0.700M
0.555M = [Na+] = [I-]
Explanation:
To solve this question we need to find the moles of sodium iodide, NaI, using its molar mass -. With the moles and the volume we can find the molarity of Na+ and I-. The molarity of the ions of silver nitrate, AgNO3 doesn't change because we are assuming the volume doesn't change:
<em>Molarity Ag⁺ = Molarity NO₃⁻ = 0.700M</em>
<em>Moles NaI -Molar mass: 149.89g/mol-</em>
20.8g NaI * (1mol/149.89g) = 0.0139 moles NaI
<em>Molarity:</em>
0.0139 moles NaI / 0.250L = <em>0.555M = [Na+] = [I-]</em>
