The mass of 187 liters of CO2 gas is 0.36 g.
Step-by-step explanation:
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
