Calculate the ph of a solution that was prepared with 1.46 g of hcl to produce 750 ml of aqueous solution.

pH = 1.27

Explanation:

The reaction is:

HCl(aq)  ⇄  H⁺(aq) + Cl⁻(aq)

We have:

m HCl = 1.46 g

V = 750 ml = 0.750 L

M HCl = 36.458 g/mol  

We know that 1 mol is equal to:

Now, we can find the concentration of HCl:

Finally, the pH of the solution is:

Therefore, the ph of a solution that was prepared with 1.46 g of hcl to produce 750 ml of aqueous solution is 1.27.

I hope it helps you!    

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
