So we definitely need the balanced chemical reaction.
00:03
We've got two moles of sodium azide, decomposing to produce three moles of nitrogen gas and two moles of sodium metal.
00:23
So the font came through all funny, but i think we're starting with 70 grams sodium azide.
00:33
To determine the volume of nitrogen gas, we first need to determine the volume of nitrogen gas, we first need to determine the, the moles of nitrogen gas, and to do that, we need to convert the grams sodium azide into moles, sodium azide.
00:51
One mole, sodium azide, has a mass of 65 .0099 grams.
01:04
Then, from the balanced chemical reaction, we see that 2 moles, sodium azide produces 3 moles.
01:13
Sodium gas.
01:18
So we're going to produce 1 .615 moles nitrogen gas.
01:26
Then we'll use the ideal gas law in order to determine the volume.
01:31
Rearranging the ideal gas law volume is equal to nrt over p...
