Answer: 1424 grams
Explanation:
![2NaN_3\rightarrow 2a+3N_2](https://tex.z-dn.net/?f=2NaN_3%5Crightarrow%202a%2B3N_2)
![Density=\frac{mass}{Volume}](https://tex.z-dn.net/?f=Density%3D%5Cfrac%7Bmass%7D%7BVolume%7D)
![1.25g/L=\frac{mass}{736L}](https://tex.z-dn.net/?f=1.25g%2FL%3D%5Cfrac%7Bmass%7D%7B736L%7D)
![Mass=920g](https://tex.z-dn.net/?f=Mass%3D920g)
Thus mass of nitrogen produced is 920 g.
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%7BMolar%20mass%7D%7D)
![\text{Number of moles of nitrogen}=\frac{920g}{28g/mol}=32.8moles](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%20of%20nitrogen%7D%3D%5Cfrac%7B920g%7D%7B28g%2Fmol%7D%3D32.8moles)
According to stoichiometry:
3 mole of
are produced from= 2 mole of ![NaN_3](https://tex.z-dn.net/?f=NaN_3)
Thus 32.8 moles of
are produced from=
of ![NaN_3](https://tex.z-dn.net/?f=NaN_3)
Mass of ![NaN_3=moles\times {\text {molar mass}}=21.9\times 65=1424g](https://tex.z-dn.net/?f=NaN_3%3Dmoles%5Ctimes%20%7B%5Ctext%20%7Bmolar%20mass%7D%7D%3D21.9%5Ctimes%2065%3D1424g)
Thus 1424 grams of sodium azide is required to produce 736 L of Nitrogen gas with the density of 1.25 g/L.
Answer:
d = 8.96 g/cm³
Explanation:
Given data:
Volume of sample = 10.0 cm³
Mass of copper = 89.6 g
Density of copper = ?
Solution:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
d = 89.6 g/ 10.0 cm³
d = 8.96 g/cm³
H-hello, allow me to help.
<h3>Question:</h3>
what type of precipitation occurs more frequently during a winter storm?
Answer:
snow and sleet
Explanation:
- freezing air temperatures near the ground and up to the clouds will cause precipitation to fall as either snow or ice.
- As rain continues to fall, it passes through a thin layer of cold air just above the surface and cools to a temperature below freezing.
