The pH is calculated using the expression: pH = - log [H3O+].
To find the concentration of [H3O+]
[H3O+] = 10^(-pH)
Solving the RHS we have 10^(-4.240) = 0.1440
Hence the concentration of H3O+ is 0.1440.

The separation of molecules. I wouldn't put that if i were you.
From the periodic table:
mass of carbon = 12 grams/mole
mass of hydrogen = 1 gram/mole
mass of oxygen = 16 grams/mole
The given compound C₆H₁₂O₆ has 6 moles of carbon, 12 moles of hydrogen and 6 moles of oxygen.
Therefore, the molar mass of the given compound will be calculated as follows:
molar mass = 6(12) + 12(1) + 6(16) = 180 grams/mole
