Carbon monoxide is a gas at 0 °c and a pressure of 1.58 × 105 pa. it is a diatomic gas, each of its molecules consisting of one carbon atom (atomic mass = 12.0 u) and one oxygen atom (atomic mass = 16.0 u). assuming that carbon monoxide is an ideal gas, calculate its density ρ.

Given temperature =

Pressure = 1.58 × ×

= 1.56 atm

ρ =

= 1.95 g/L

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.
