The rate of disappearance of chlorine gas : 0.2 mol/dm³
<h3>Further explanation</h3>The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.
For reaction :
The rate reaction :
Reaction for formation CCl₄ :
<em>CH₄+4Cl₂⇒CCl₄+4HCl</em>
<em />
From equation, rate of reaction = rate of formation CCl₄ = 0.05 mol/dm³
Rate of formation of CCl₄ = reaction rate x coefficient of CCCl₄
0.05 mol/dm³ = reaction rate x 1⇒reaction rate = 0.05 mol/dm³
The rate of disappearance of chlorine gas (Cl₂) :
Rate of disappearance of Cl₂ = reaction rate x coefficient of Cl₂
Rate of disappearance of Cl₂ = 0.05 x 4 = 0.2 mol/dm³
Answer:
Mass % of the solution = 7.1067 %
Explanation:
Given :
Molarity of nitric acid solution = 1.85 M
Density of the solution = 1.64 g/mL
<u>Molarity of a solution is defined as the number of moles of solute present in 1 liter of the solution.</u>
Lets, consider the volume of the solution = 1 L
Thus,
Moles of nitric acid present in the solution:
So,
Moles of Nitric acid = 1.85 moles
Molar mass of nitric acid = 63 g/mol
The mass of Nitric acid can be find out by using mole formula as:
Thus,
<u>Mass of Nitric acid = 116.55 g</u>
Also,
Given : Density = 1.64 g/mL
Also, 1 L = 10³ mL
Volume of the solution is 1000 mL
So, mass of the solution:
<u>Mass of the solution = 1640 g</u>
Mass % is defined as the mass of solute in 100 g of the solution. The formula for the calculation of mass % is shown below:
So,
<u>Mass % = 7.1067 %</u>
