0.25 mol of nitric acid is used to make a 0.10 M nitric acid solution. What is the total volume of nitric acid in liters
Lelu [443]

Answer:

2.5 L will be the volume of HNO₃

Explanation:

To find out the total volume of nitric acid in liters we begin from molarity.

HNO₃ solution is 0.10 M

This means that 0.10 moles are contained in 1L of solution.

As we used 0.25 moles of nitric, let's determine the volume by a rule of three:

0.10 moles of nitric acid are contained in 1L of solution

0.25 moles of nitric acid will be contained in (0.25 . 1) / 0.1 = 2.5 L

What is the free energy change if the ratio of the concentrations of the products to the concentrations of the reactants is 22.3
snow_lady [41]

The free energy change(Gibbs free energy-ΔG)=-8.698 kJ/mol

<h3>Further explanation</h3>

Given

Ratio of the concentrations of the products to the concentrations of the reactants is 22.3

Temperature = 37 C = 310 K

ΔG°=-16.7 kJ/mol

Required

the free energy change

Solution

Ratio of the concentration : equilbrium constant = K = 22.3

We can use Gibbs free energy :

ΔG = ΔG°+ RT ln K

R=8.314 .10⁻³ kJ/mol K

\tt \Delta G=-16.7~kJ/mol+8.314.10^{-3}\times 310\times ln~22.3\\\\\Delta G=-8.698~kJ/mol
