Question

A 25 mL sample of 0. 100 M HNO3 completely reacts with NaOH according to this equation: HNO3(aq) NaOH (aq) ⟶ NaNO3(aq) H2O(l) How many moles of HNO3 are in the sample? mol HNO3.

Answer 1

.0025

Step-by-step explanation:

1. For this type of equation you must convert mL to L
2. 25 mL converts to .025 L
3. Next set up the equation to find the mols of HNO3 which is Volume × Molarity = Mol
4. The equation is: .025 × .100 = .0025 mol HNO3
