What is the H3O+ in a solution that contains 1.48 g HNO3 in 0.560 L of solution?

Well, H3O+ is like the VIP club in a solution. It's formed when a water molecule (H2O) decides to get a little wild and invites its bestie, a hydrogen ion (H+), to join the party. So, in this case, we need to figure out how many moles of HNO3 are in the solution and convert that to moles of H3O+.

First, let's determine the number of moles of HNO3. We can use its molar mass, which is 63.01 g/mol.
So, 1.48 g of HNO3 would be:

1.48 g / 63.01 g/mol = 0.0235 mol

Since HNO3 is a strong acid, it completely dissociates in water, forming one H+ ion per molecule of HNO3. Hence, we have 0.0235 mol of H3O+ ions.

Now, let's calculate the concentration of H3O+ in the solution. We know the volume of the solution is 0.560 L.

Concentration (C) is given by moles (n) divided by volume (V):

C = n/V
C = 0.0235 mol / 0.560 L
C ≈ 0.042 mol/L

So, the concentration of H3O+ in the solution is approximately 0.042 mol/L. They sure know how to keep the acidity in check at that party!

To find the concentration of H3O+ in the solution, we will first need to calculate the number of moles of HNO3 in the solution.

Step 1: Calculate the molar mass of HNO3 (nitric acid).
H = 1.01 g/mol
N = 14.01 g/mol
O = 16.00 g/mol

Therefore, the molar mass of HNO3 = (1.01 * 1) + (14.01 * 1) + (16.00 * 3) = 63.02 g/mol.

Step 2: Convert the given mass of HNO3 to moles.
Mass of HNO3 = 1.48 g.
Number of moles of HNO3 = mass / molar mass
= 1.48 g / 63.02 g/mol
≈ 0.0234 mol.

Step 3: Find the concentration of H3O+.
Concentration (C) = Number of moles / Volume of solution
= 0.0234 mol / 0.560 L
≈ 0.0418 mol/L.

Therefore, the concentration of H3O+ in the solution is approximately 0.0418 mol/L.

To find the concentration of H3O+ in the solution, you need to calculate the number of moles of HNO3 and convert it into moles of H3O+.

1. Calculate the number of moles of HNO3:
Number of moles = mass / molar mass
The molar mass of HNO3 is 63.01 g/mol.
Number of moles of HNO3 = 1.48 g / 63.01 g/mol

2. Convert the moles of HNO3 to moles of H3O+:
The balanced chemical equation for HNO3 is:
HNO3 + H2O → H3O+ + NO3-
From the equation, it is evident that every mole of HNO3 produces one mole of H3O+.
So, the number of moles of H3O+ is equal to the number of moles of HNO3.

3. Calculate the concentration of H3O+:
Concentration (in moles per liter) = moles / volume (in liters)
Concentration of H3O+ = number of moles of H3O+ / 0.560 L

Now, you can follow these steps to calculate the concentration of H3O+ in the given solution containing 1.48 g HNO3 in 0.560 L of solution.

moles = grams/molar mass.

Calculate moles HNO3.

M = moles/L
Calculate M

Since HNO3 is a strong acid, the H3O^+ will be the same as the HNO3.
