A student measures the mass of an object to be 5.7 grams. What would the final density be if the volume of the object was 45.0 mL?
A. 0.126 g/mL
B. 79g/ml
C. 0.56 g/ml
D. 8.5g/ml

0.126 g/ml

Explanation:

given mass =5.7 g

volume =45.0 ml

now we density=m/v

d=5.7/45.0

d=0.126 g/ml

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.
