The osmotic pressure at STP of a solution its volume 800 ml of NaCl (aq) containing 35.5 g of NaCl is : a- 54.56 atm b- 58.67 atm c- 55.96 atm d- 59.88 atm

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

Molecular iodine, i2(g), dissociates into iodine atoms at 625 k with a first-order rate constant of 0.271 s−1. part a part complete what is the half-life for this reaction?

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.
