What is the pH of a solution containing 0.16 m hno2 and 0.50 m nano2?

pH =pKa - log [ cA / cB ]
where:
pKa is the negative logarithmic value of the weak acid equilibrium consant,
cA is the molar concentration of the weak acid conjugate (acetic acid) and
cB is the molar concentration of the weak base conjugate (acetate).
So
pH = 4.77 -log(0.16 / 0.23) = 4.77 - ( -0.158) = 4.77 + 0.158 = 4.93

To calculate the pH of the solution, you need to consider the dissociation of both acids. Nitrous acid (HNO2) is a weak acid, while sodium nitrite (NaNO2) is a salt of a weak acid. Use the given concentrations to calculate the initial concentration of H+ ions from HNO2, then consider the effect of the NaNO2 on the pH by reacting with any excess H+ ions. Finally, calculate the pH using the equilibrium concentrations of the resulting species.

Is a milliliter small or big?
it really matters what your comparing it to. Although, as far as i know it is small. A liter is about the same as a quart. A milliliter is 1/1000 of a liter or approximately .016 of an ounce. It's very small..
What is the mass in grams of 1.3 moles of silver?
There are 107.9 grams in one mole of pure silver. 107.9 a.m.u. is the average mass of isotopes of the element silver Answer to another (= not this one) question: The atomic number is the number of grams in a mole of any element. Hydrogen has an atomic number of 1 so a mole of hydrogen (okay, a half-mole of H2) weighs 1 gram. [ Silver is not Hydrogen ! and an atom is not a molecule]
