Answer:
96,532,000,000,000,000,000,000 ions.
Explanation:
- Assume the highest concentration of HCl in the stomach (160 mmol/L) that is in the canaliculi.
- This means that 1.0 L of the stomach acid contains 0.160 mol.
- Every 1.0 mole of HCl contains Avogadro’s number of molecules (6.022 x 10²³) molecules.
- Every 1.0 molecule of HCl contains 1.0 H⁺ ion.
<u><em>Using cross multiplication:</em></u>
1.0 mole of HCl → 6.022 x 10²³ H⁺ ions.
0.160 mole of HCl → ??? H⁺ ions.
∴ The no. of H⁺ ions in 1 liter of stomach acid = (6.022 x 10²³ H⁺ ions)(0.160 mole of HCl) / (1.0 mole of HCl) = 9.6352 x 10²² ions = 96,532,000,000,000,000,000,000 ions.
For the molarity and the percentage of the mass of kcl are mathematically given as
%m/m = 23.1%, molarity = 3.38M
<h3>What is the molarity?</h3>
Generally, the equation for the percentage of the mass of kcl is mathematically given as
(mass of kcl/mass of solution)x 100
therefore
%m/m = (6.31/27.29)x100
%m/m = 23.1%
The molarity
(no of mol/ vol of sol)
molarity = 0.0846mol/0.0250 L
molarity = 3.38M
In conclusion, the molarity is given as
molarity = 3.38M

Answer: Weak acids are poor conductors of electricity.
Explanation:
Weak acids are defined as the acids which dissociate weakly or partially when dissolved in water (polar solvent).
For example, 
Due to less dissociation there will be less number of ions present in a solution of weak acid. As a result, a weak acid will be poor conductor of electricity.
As electricity is the flow of ions.
Thus, we can conclude that weak acids are poor conductors of electricity.
