Student prepares a 0.207 g sample of the nonvolatile solute caryophyllene by dissolving the substance in 1.00 g of chloroform (kb = 3.63c/m). the boiling point of chloroform increases by 3.68c. determine the molar mass (g/mol) of caryophyllene?

204.2 g/mol

Explanation:

Elevation in boiling point is given by:

=  Elevation in boiling point =  

= boiling point constant  =

m = molality

where,

n = moles of solute =

  = weight of solvent in g  = 1g

Molality =

Putting in the values we get,

The molar mass of caryophyllene is 204.2 g/mol.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
