Chemistry

Moles are found in a 350.mL solution of 13.5M $HNO_{3}$ are 4.725 mol.

Explanation:

Given: Volume = 350 mL (1 mL = 0.001 L) = 0.350 L

Molarity = 13.5 M

Molarity is the number of moles of a substance present in a liter of solution.

Therefore, moles of $HNO_{3}$ present in the given solution are calculated as follows.

$Molarity = \frac{moles}{Volume (in L)}\\13.5 M = \frac{moles}{0.350 L}\\moles = 4.725 mol$

Thus, we can conclude that moles found in a 350.mL solution of 13.5M $HNO_{3}$ are 4.725 mol.
