The boiling point of water is 100.0°C at 1 atmosphere. How many grams of ammonium nitrate (80.06 g/mol), must be dissolved in 283.0 grams of water to raise the boiling point by
0.350°C? Refer to the table for the necessary boiling or freezing point constant.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
