The volume of chlorine required is 7.71 L.
The reaction between phosphorus and chlorine is:
2P + 5Cl₂→ 5PCl₅
Therefore, 2 moles of P requires 5 moles of chlorine to react with it.
Given mass of P =3.39 g
Molar mass of P=30.97 g/mol
No. of moles of P = given mass/ molar mass = 3.39 / 30.97 = 0.109 moles
2 moles of P requires 5 moles of chlorine
0.109 moles of P will require 0.109 x 5/2 = 0.2725 moles of chlorine
According to ideal gas equation
PV=nRT
2.04 x V = 0.2725 x 0.0821 x 703
V = 0.2725 x 0.0821 x 703 / 2.04
V = 7.71L

Answer:
A red giant is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K or lower.
For us to accurately determine what compound
this is, additional info must be given. However I can suggest two compounds
which have molecular mass of about 30.07 g/mol.
1. It could be NO or nitric oxide.
The molecular mass is 16 + 14= 30 g/mol
But if we search the exact weight, it is 30.01 g/mol
2. It could also be (CH3)2 or ethane.
The molecular mass is 2*12+ 6*1= 30 g/mol
But if we search the exact weight, it
is 30.07 g/mol.
<span>So we could say it more likely to to be (CH3)2 </span>
Probably CH(subscript)4... :) It's Methane
