How many grams of nan3 are required to produce 19.0 ft3 of nitrogen gas, about the size of an automotive air bag, if the gas has a density of 1.25 g/l?

The  balanced chemical reaction is given as:

Now, convert into litres.

So,

Density is equal to the ratio of mass to the volume.

where, M = mass and V= volume

Substitute the value of density and volume in formula to get the value of mass.

Now, number of moles of gas=

=

According to the reaction, 2 moles of sodium azide gives 3 moles of nitrogen gas.

Now, in 24.00 moles of nitrogen gas produced from= of nitrogen gas, moles of sodium azide.

number of moles of sodium azide  =

Mass of sodium azide in g  =  .

=

=

Thus, mass of sodium azide which is required to produce of nitrogen gas  =

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
