How many moles of oxygen (O2) are present in 33.6 L of the gas at 1 atm and 0°C?

1.50 moles of oxygen are present.

Explanation:

According to ideal gas equation:

P = pressure of gas = 1  atm

V = Volume of gas = 33.6 L

n = number of moles = ?

R = gas constant =

T =temperature =

Thus 1.50 moles of oxygen are present.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
