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 \times ( 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)\times(0.0821)\times(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

How do white blood cells fight pathogens?
jonny [76]
White blood cells work in two ways; they can ingest or engulf pathogens and destroy them by digesting them. White blood cells can also produce antibodies to destroy particular pathogens by clumping them together and destroying them. They also produce antitoxins that counteract the toxins released by pathogens.
