Answer: D=4.35g/L
Explanation:
The formula for density is
. M is mass in grams and V is volume in liters.
Since we are give pressure and temperature, we can use the ideal gas law to find moles/volume. FInding moles/volume would give us the base for density. All we would have to do is convert moles to grams.
Ideal Gas Law: PV=nRT
![\frac{n}{V} =\frac{P}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7BV%7D%20%3D%5Cfrac%7BP%7D%7BRT%7D)
![\frac{n}{V}=\frac{1.50 atm}{(0.08206Latm/Kmol)(25+274.15K)}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7BV%7D%3D%5Cfrac%7B1.50%20atm%7D%7B%280.08206Latm%2FKmol%29%2825%2B274.15K%29%7D)
![\frac{n}{V} =\frac{0.061309mol}{L}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7BV%7D%20%3D%5Cfrac%7B0.061309mol%7D%7BL%7D)
Now that we have moles, we can use molar mass of chlorine gas to find grams.
![0.061309mol*\frac{71.0g}{mol} =4.3529g](https://tex.z-dn.net/?f=0.061309mol%2A%5Cfrac%7B71.0g%7D%7Bmol%7D%20%3D4.3529g)
With our grams, we can find our density.
![D=\frac{4.3529g}{L}](https://tex.z-dn.net/?f=D%3D%5Cfrac%7B4.3529g%7D%7BL%7D)
We need correct significant figures so our density is:
![D=\frac{4.35g}{L}](https://tex.z-dn.net/?f=D%3D%5Cfrac%7B4.35g%7D%7BL%7D)
A change from physical change into chemical change not sure hope this helps
