Calculate the vapor pressure at 25° C of a solution containing 99.5 g sucrose
(C12H22011) and 300.0 mL water. The vapor
pressure of pure water at 25° C is 23.8 torr.
Assume the density of water to be 1.00
g/mL.

Which of these properties, used alone, would be least useful in identifying most minerals? a. color b. luster c. streak d. density

What is the mass of sodium in 3 moles of sodium chloride

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.
