Asolution is made by dissolving 10.2 grams of glucose (c6h12o6) in 0.315 kilograms of water. if the molal freezing point constant for water (kf) is -1.86 °c/m, what is the resulting δtf of the solution? show all of the steps taken to solve this problem.

1 a

2 d

3 a

4 c

explanation:

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
