if 5.20 g of hcl is added to enough distilled water to form 3.00 l of solution, what is the molarity of the solution? [molecular weight: hcl, 36.46 amu]

2. how is heavy water different from normal water

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

In the diagram here that represents the reaction, which reactant, a or b, is the limiting reagent?
