This method relies on the exothermic reaction of lithium hydroxide with carbon dioxide gas to create lithium carbonate (Li2CO3) solid and water (H2O).
might be wrong but....oh well
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:
0.705 g/cm³
Explanation:
Step 1: define density
The (volumetric mass) density of a sample or substance, is this sample or substance its mass per unit volume and can be defined through following formula:
ρ = m/v
with ρ = density (kg/m³)
m = mass of the substance (kg )
v = volume (m3)
Step 2: change datat SI-units
10.0 cm³ = 10^-5 m³
7.05 g = 0.00705 kg
ρ = 0.00705 kg / 10^-5 m³ = 705 kg / m³
To convert this to g/cm³ we have to divide by 1000
ρ = 0.705 g/cm³
To control this we calculate 7.05g / 10cm³ = 0.705 g/cm³
The desnity of the alcohol is 0.705 g/cm³
