Moles nitric acid =????
Please I need help

Answer 1

0.08 moles

Step-by-step explanation:

The number of moles of nitric acid used can be calculated using the formula:

moles = concentration x volume

where concentration is in moles/liter and volume is in liters.

Since the volume of nitric acid used is given in milliliters (5 mL), we first need to convert it to liters:

5 mL = 5 x 10^-3 L

Now, we can calculate the number of moles of nitric acid used:

moles = 16.0 M x (5 x 10^-3 L) = 0.08 moles

So, 0.08 moles of concentrated nitric acid (16 M) were used.
