Answer:
0.316
Explanation:
ph --> H+ --> Oh-
H+ = 10^-ph
= 10^-12.5
= 3.16 x 10^-13
now for oh-
oh - = 1 x 10^-14 / 3.16 x 10^-13
= .0316
The answer is C3H603 and C2H402.
When molality = no.of moles of solute/weight Kg of solvent
and when we have the no. of moles of solute = 8.1 moles
and the weight Kg of the solvent =4847 g /1000 = 4.847 Kg
so by substitution :
Molarity = 8.1m / 4.847Kg = 1.67 M
