What is the mass of 187 liters of CO2 gas? The volume is measured at STP.
1 answer:
The mass of 187 liters of CO2 gas is 0.36 g.
<u>Explanation:</u>
The molecular weight of CO2 is 44 g / mol.
1 kg of CO2 = 1000 g ( 1 mole / 44 g) = 22.7 mole of CO2.
By using the ideal gas equation,
PV = nRT
V = nRT / P
where P represents the pressure,
V represents the volume,
T represents the temperature,
R represents the ideal gas constant,
n represents the amount of substance.
V = (22.7)(0.0821)
(273.15) / 1
V = 509.6 L of CO2 at STP
Mass = (187 L of CO2 gas) / (509.6 L of CO2 at STP)
= 187 / 509.6
mass = 0.36 g

Explanation:
The given data is as follows.
Solvent 1 = benzene, Solvent 2 = water
= 2.7,
= 100 mL
= 10 mL, weight of compound = 1 g
Extract = 3
Therefore, calculate the fraction remaining as follows.
=
=
=
Hence, weight of compound to be extracted = weight of compound - fraction remaining
= 1 -
= 0.00001
or, =
Thus, we can conclude that weight of compound that could be extracted is .
