Suppose that you made the experimental errors described below. Would these errors lead you to obtain a higher or lower molar mass of carbon dioxide? Explain your reasoning. A. Some CO2 gas leaked out of Flask B as you went to the balance room to weigh it.
B. When filling Flask B with water you did not fill it up to the brim, leaving some air at the top.

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.
