Calculate the volume of 89.09 grams of chlorine gas in STP.
And
Calculate the density of propane gas in STP.
STP stands for standard temperature and pressure which is 1 atm and 273 K (0 C C).
First we use the ideal law of gas: PV = nRT
P = pressure = 1 atm
V = volume (what you will get)
n = # of (counted in grams)
R is a constant R = 0.08296 Latm / molK.
T = temperature = 273 K.
89.09 g Cl2 (1 mol Cl2) / (70.9) = 1.26 mol Cl2
PV = nRT
(1 atm) (V) = (1.26 mol) (0.08206 Latm / molK) (273 K)
V = 28.25 liters
And for another, use the formula derived from the form PV = nRT.
Because D = m / V
And n = m / MM (MM molar is m)
Then PV = (m / MM) RT
PVMM = MRT
PMM = (mRT) / V
PMM = (m / V) RT
PMM = DRT
D = (MM P) / RT
Molar propane (C3O8) is 164.03 grams.
D = (164.03 g) (1 atm) / (0.08206 Latm / molK) (273 K)
Then D = 7.32 g / L
What does stp mean?
STP stands for Standard Temperature and Pressure. Typically 0 سیل C for temperature and 1 atm for pressure.
This helps in calculating the mole as you can use the number 22.4 L as in STP you need 22.4 L volume for each mole of gas.
So for chlorine (Cl_2), change m first.
One sesame chlorine contains 35.45 grams of chlorine. Where chlorine is generally diatomic and is present as Cl_2, 1 mole of chlorine gas actually contains 70.9 grams of chlorine.
80.09 grams of chlorine / 70.9 (grams / mol) = 1.13 total_2. Use only number 22.4 to convert to liters.
1.13 Cl2 * 22.4 liters / mol = 25.312 liters Cl_2 volume
With the issue of density, it is a bit more complicated. You know that 1 sesame is equal to 22.4 liters, so you have to calculate m of one sesame of propane, which is 44.11 grams in 22.4 liters. The most common unit of measurement is X grams / 1 liter, so you have to change that, although 44.11 grams / 22.4 liters is technically a unit of density.
To do this, just divide the top and bottom by 22.4.
44.11 / 22.4 = 1.97 grams.
22.4 / 22.4 = 1 liter.
Therefore, your final density reading will be 1.97 grams per liter.
