40 liters is equal to?
A. 40 cm3
B. 40 m3
C. 4,000 ml

none of the options are correct

Explanation:

For cm3

1L = 1000cm3

40L = 40 x 1000 = 40000cm3

For m3

1L = 0.001m3

40L = 40 x 0.001 = 0.04m3

For mL

1L = 1000mL

40L = 40 x 1000 = 40000mL

From the calculations above, none of the options are correct

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.
