3Cl2 + 2Al ---> 2AlCl3
you're pretty much trying to find the lcm to balance the equation
aka you have 2 Cl's on one side and 3 on the other...
lcm=6 so put a 3 before Cl2 and a 2 before AlCl3 (since thats one big compound you cant divide it)
now since Al has 2 on one side, you need to make sure it has the same amound on the other... so 3, 2 --> 2
X= 2.0atm when u substitute for V1P1=V2P2
Answer:
2.448 * 10^-5M
Explanation:
To calculate the concentration of the solution, we apply the Beer Lambert law equation.
That is A = £LC
Where £ represents the molar extinction coefficient.
We identify the values as follows:
A = absorbance = 0.735
L = cell length = 1.30
£ = 23100
c = concentration = ?
Rearranging the equation, c = A/£L
c = 0.735/(23,100 * 1.3)
c = 2.448 * 10^-5 M
A is the correct answer i really hope this helps!
