find the normal boiling point of 0.57 m C12H22O11(aq). the boiling point constant of water is 0.51 K . kg/mol. answer in units of C(degree)
An aqueous solution freezes at -5.64 C (degree). what is the molality of the solution? assume that there is no dissociation of the solute and the kf is 1.69 K . kg/mol. answer in units of C (degree)
please if you understand either one can you explain how you got the answer thanks.
1) the law of constant composition states that compounds contain atoms in fixed proportions.
2) a combustion analyzer measures the molar mass of a compound
3) the information provided by a combustion analyzer and mass spectrometer may be used to determine the molecular formula of a compound
4) if the molecular formula of a compound is C3H8NS the its empirical formula is also C3H8NS
