Density is defined as mass per unit volume.
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
Step first:
Since, 78.0 percent by volume is present in the air which implies there are 78 moles of
present in 100 moles of air.
Now,
Mole fraction of =
Mole fraction =
= 0.78
Partial pressure is equal to the multiplication of total pressure and mole fraction.
Partial pressure = (as 1 atm is atmospheric pressure)
= 0.78 atm.
Step second:
Henry's law constant is calculated by:
where,
is solubility of gas
is partial pressure of gas
is henry's law constant
Substitute the value of solubility and partial pressure to find the value of Henry's law constant in above formula:
k =
=
Thus, Henry's Law constant is .
