What instantaneous release on the ground, in g, of acrolein will result in a downwind concentration 1500 m immediately downwind on the ground equal to 0.05 ppm? It is a bright sunny day with a wind speed of 3.5 m/s. Assume rural conditions, a temperature of 25°C, and 1 atm pressure. Where does the maximum concentration occur on the ground for this release?

Ibelieve the answer is relative humidity because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage. latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.

Answer from: Quest

answer: zinc is the substance which has a volume of 1.38 $cm^{3}$ .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e. $density = \frac{mass}{volume}$

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula $volume = \frac{mass}{density}$ .

hence, the volume of aluminium will be = $\frac{4.60}{2.70} cm^{3}$ which comes out to be 1.703 $cm^{3}$ .

similarly, volume of zinc, chromium, and nickel will be 1.378 $cm^{3}$ , 0.869 $cm^{3}$ , and 0.356 $cm^{3}$ respectively.
