HCl solution, about 250 mL in volume. The pH of the solution is 1.37. Calculate the molar concentration of HCl in this solution. Please use the scientific presentation of the numerical answers (i. e., 1.23x 102), and round your answers to two decimal places.

Molar concentration of HCl in this Solution = 0.01 molar

Explanation:

Given pH = 1.37

So Concentration of H⁺ is equal to = 0.042 molar

Volume of HCl solution = 250 ml

Since,

             1000 ml solution contain 0.042 mole of HCl

              250 ml solution contain = = 0.01 molar

Round off value = 0.01

Molar concentration of HCl in this Solution = 0.01 molar

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.  

i think its 100.

hope this !
