A 5.60 g sample of a weak acid with Ка 1.3 x 10-4 was combined with 5.00 mL of
5.80 mol L-1 NaOH and the resulting solution
was diluted to 750 mL. The measured pH of the
solution was 4.35.
What is the molar mass of the weak acid

Summarize possible ways in which phases of matter could combine to form a solution.

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?
