5.58 X Litres is the volume, in liters, occupied by 0.015 molecules of oxygen at STP.
Explanation:
Data given:
molecules of oxygen = 0.015
number of moles of oxygen =?
temperature at STP = 273 K
Pressure at STP = 1 atm
volume = ?
R (gas constant) = 0.08201 L atm/mole K
to convert molecules to moles,
number of moles =
number of moles = 2.49 x
Applying the ideal gas law since the oxygen is at STP,
PV = nRT
rearranging the equation:
V =
putting the values in the rearranged equation:
V =
V = 5.58 X Litres.

Explanation:
Chlorine is a member of the halogen family known as a toxic yellowish green gas. Inhalation of chlorine for a prolonged period of time leads to pulmonary edema. If a person comes in contact with compressed liquid chlorine the person may experience frostbite of the skin and eyes.
However chlorine is very useful in water disinfection and is preferred in water treatment because it provides residual disinfection of the treated water.
Chlorine gas may be dissolved in NaOH to form oxochlorate I which is used as a bleach in cleaning.
