Vanillin (used to flavor vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest amount. the threshold limit is 2.0 × 10−11 g per liter of air. if the current price of 50.0 g of vanillin is $115, determine the cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 5.47 × 107 ft3.

Explanation:

1. Convert cubic feet to litres

2. Calculate the mass of vanillin

3. Calculate the cost of the vanillin

the answer would be a

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
