Answer: The concentration of the diluted solution is 1.566M.
Explanation:
The dilution equation is presented as this: .
·M= molarity (labeled as M)
·V= volume (labeled as L)
·s= stock solution (what you started with)
·d= diluted solution (what you have after)
Now that we know what each part of the formula symbolizes, we can plug in our data.
We cannot leave it like this because the volumes must be in Liters, not milliliters. To convert this, we divide the milliliters by 1000.
Now that we have the conversions, let's plug them into the equation.
The only thing that we need to do now is actually solving the answer.
From the work shown above, the answer is 1.566M.
I hope this helps!! Pls mark brainliest :)
Answer is attached below ( sorry for mistake )
The enthalpy change of the reaction when sodium hydroxide and sulfuric acid react can be calculated using the mass of solution, temperature change, and specific heat of water.
The balanced chemical equation for the reaction can be represented as,
Given volume of the solution = 101.2 mL + 50.6 mL = 151.8 mL
Heat of the reaction, q = Δ
m is mass of the solution = 151.8 mL *
C is the specific heat of solution = 4.18
ΔT is the temperature change =
q =
Moles of NaOH = NaOH
Moles of =
Enthalpy of the reaction =
