The concentrated H2SO4 of 155g dissolved in enough amount of water if acidic solution is 2.3L

a) what is the mole of H2SO4
b) what is the concentration H2SO4
c) what is the concentration of H+(H3O+) created in the solution
d) what is the PH value of solution
e) what is the concentration of SO4 ion

To answer these questions, we need to first determine some key information and use various formulas relating to molarity and pH calculations.

a) To calculate the moles of H2SO4, we need to use the formula:

moles = mass / molar mass

Given that the mass of the H2SO4 is 155g, we need to find the molar mass of H2SO4, which is:

Molar mass(H2SO4) = (2 * molar mass(H)) + molar mass(S) + (4 * molar mass(O))

Using the periodic table, we find:

Molar mass(H2SO4) = (2 * 1.0078 g/mol) + 32.06 g/mol + (4 * 16.00 g/mol) = 98.09 g/mol

Now, we can calculate the moles of H2SO4:

moles = 155g / 98.09 g/mol

b) To determine the concentration of H2SO4, we need to use the formula:

concentration = moles / volume

Given that the volume of the solution is 2.3 L, we can calculate the concentration:

concentration = moles / 2.3 L

c) The concentration of H+(H3O+) in the solution is the same as the concentration of H2SO4. Therefore, the concentration of H+(H3O+) created in the solution is the same as the concentration calculated in (b).

d) The pH value of a solution is determined using the equation:

pH = -log10[H+]

Given that we know the concentration of H+(H3O+), we can substitute it into the formula to find the pH value.

e) The concentration of SO4 ions can be determined by considering that for each mole of H2SO4, there is one mole of SO4 ions. So, the concentration of SO4 ions is the same as the concentration of H2SO4 calculated in (b).

Remember, when performing these calculations, it's important to keep track of units and use appropriate conversion factors if necessary.
