A and B as well C are the compounds.
Explanation:
- A seems to be a compound, very least, it appears to contain carbon and oxygen.
- C seems to be a compound, containing respectively oxygen as well as carbon.
- B isn't always described by that of the information provided, it is therefore presumably a compound because there are few components as white solid particles.
So that the above is the correct answer.
Concentration can be expressed in different forms: molarity, molality, normality, percentage, part per million and many more. For molality, it is a unit of concentration expressed as moles of solute per kilogram of solvent. Therefore,
0.3 = moles solute/0.10 kg solvent
moles solute = 0.03 moles
