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
