How many molecules are found in 1.32 mol of nacl?

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

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.
