Answer: 367 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number
of particles.
Enthalpy of vaporization is the amount of heat released when 1 mole of substance is converted from liquid to gaseous state.
Given : Enthalpy of vapourization of
= 17.4 kJ/mol
To calculate the number of moles, we use the equation:


1 mole of
produces heat = 17.4 kJ
8.3 moles of
produces heat = 
Given : Enthalpy of vapourization of
= 6.0 kcal/mol =
(1kcal=4.184kJ)
25.104 kJ heat is produced by = 1 mole of
144 kJ heat is produced by =
of
Mass of 
Thus 367 grams of
must be evoparated o remove as much heat as evaporation of 1.00 kg of

Answer:
Erosion of undersea stalagmites and stalactites. Erosion of the face of a cliff by waves. Rising of magma from the seafloor.
Explanation:
Sugar, sucrose (C12H22O11: a disaccharide, composed of the two monosaccharides: glucose and fructose), is odorless, that is, it lacks odor. When heated a phase change occurs resulting in melting of a thick syrup.
