47.0 mL of an HBr solution were titrated with 37.5 mL of a 0.215 M LiOH solution to reach the equivalence point. What is the molarity of the HBr solution?

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
