A flask containing 5.00mL of 3 M HCl solution requires 14.45mL of 1.00 M NaOH for titration. How many moles of HCl are present in the solution? The density of 3 M HCl is 1.05g/mL

I rechecked this question, and I wrote it down correctly. I couldn't understand the process of finding the correct answer, so i would appreciate the help.

Unless I have really missed something, and I don't think I have, there is no correct answer. There is no unknown to determine. 5.00 mL of 3 M HCl CAN'T require 14.45 mL of 1.00 M NaOH. moles = M x L. For HCl that is 0.005 x 3.00 M = 0.015 moles.

NaOH titrated it.
0.01445 x 1.00 M NaOH = 0.01445 moles. So if you believe the HCl is labeled correctly the answer is 0.015 moles. If you believe the titration to be correct, there is 0.01445 mole. WAIT!
Could this be a problem with significant figures? 3 M x 5.00 = 0.015 mole but to only one significant figure (from the 3M) this would be rounded to 0.02 mole (or 0.01 depending upon the rule you follow).
14.45 mL x 1.00 M = 0.01445 and you are allowed three s.f. which would round to 0.0144 mole NaOH = 0.0144 mole HCl. The NaOH is more accurately measured; therefore, the NaOH titration would rule. Significant figures COULD be the problem in which case the answer is 0.0144 mole HCl.

Oh, chemistry jokes? I guess you could say this question has some "mole-mentum!" So, let's get into it. To find the number of moles of HCl, we first need to calculate the number of moles of NaOH used in the titration. Are you ready? Let the titration begin!

Given:
Volume of 1.00 M NaOH used: 14.45 mL
Concentration of NaOH: 1.00 M

Now, let's calculate the moles of NaOH:
Moles of NaOH = Concentration × Volume (in liters)
Moles of NaOH = (1.00 mol/L) × (14.45 mL/1000 mL/L)
Moles of NaOH = 0.01445 mol

But wait! We're not done yet. Since the reaction between HCl and NaOH is a 1:1 ratio, this means that the moles of NaOH is equivalent to the moles of HCl. It's a titration match made in heaven.

So, the number of moles of HCl present in the solution is also 0.01445 mol. Ta-da! We've got our answer.

Remember, always keep your chemistry enthusiasm bubbling.

To find the number of moles of HCl present in the solution, we can use the formula:

moles = concentration (M) * volume (L)

First, we need to convert the volume of HCl solution from milliliters (mL) to liters (L):

volume of HCl solution = 5.00 mL * (1 L / 1000 mL) = 0.005 L

Now, we can calculate the number of moles of HCl:

moles of HCl = 3 M * 0.005 L = 0.015 moles

So, there are 0.015 moles of HCl present in the solution.

Note: The density of 3 M HCl is not required to calculate the number of moles of HCl in this case. It is used to convert between volume and mass when necessary.
