I'm not sure why I'm having trouble with these step-by-step questions. It keeps marking them wrong.

The flask contains 10.0 mL of HCI and a few drops of
phenolphthalein indicator. The buret contains
0.230 M NaOH. It requires 16.6 mL of the NaOH solution
to reach the end point of the titration.
What is the concentration of the HCI solution?

Step 1: How many moles of NaOH are present in 16.6 mL
of 0.230 M NaOH?
moles of NaOH:
mol

Step 2: How many moles of HCI are in the
10.0 mL sample?

Step 3: What is the concentration of the HCI solution?
