Determine the following for sucrose (c2h2,0,1) solution. a) the number of moles in 200ml of a 0.100m solution. b) the volume of a 1.25m solution containing 0.100 moles of sucrose. c) the molarity of a solution containing 10 g of sucrose in 500ml of water

more info ? ? i don't understand what the question is

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.
