How can I convert a rate constant from mol to t/M.I have 0.00012 mol of AcH
present at 5min .Know I want to calculate the concentration at this time ( [AcH]t / M ) . How would I work this out .Please help this is for a lab write up for tomorrow .
To convert a rate constant from mol to t/M, you need to consider the stoichiometry of the reaction. The rate constant is typically given in units of mol/L·s, which represents the concentration of the reactant and the time. To convert it to t/M, you need to divide the rate constant by the molar mass of the reactant.
In your case, you have 0.00012 mol of AcH present at 5 minutes. To calculate the concentration at this time ([AcH]t / M), you need to determine the volume of the solution.
Let's assume you have a known volume of solution, V (in liters). First, calculate the concentration of AcH at 5 minutes:
Concentration = moles of AcH / volume of solution
Concentration = 0.00012 mol / V L
Now, divide the concentration value by the molar mass of AcH to convert it to t/M:
[AcH]t / M = (0.00012 mol / V L) / (molar mass of AcH g/mol)
By performing this calculation, you will obtain the concentration of AcH at 5 minutes in t/M units. Remember to substitute the appropriate values for the volume of the solution and the molar mass of AcH.
Additionally, make sure that all units are consistent throughout your lab write-up and double-check any experimental values used in the calculation to ensure accuracy.
