The same as the mass of 1 mole of carbon and 2 moles of chlorine gas.


#"C"(s) + "2Cl"_2(g) rarr "CCl"_4(l)#

A mole of carbon has a mass of #12.011*g#.

A mole of chlorine gas has a mass of #71.0*g#.

You do the math.

The molar mass of carbon tetrachloride is 153.8 g/mol.


The chemical formula for carbon tetrachloride is #"CCl"_4"#. We will use its formula to determine its molar mass.

The molar mass of a compound is determined by multiplying the subscript for each element by its molar mass and adding the results. The molar mass of an element is its atomic weight on the periodic table in g/mol.

By consulting the periodic table, you will be able to determine the molar masses of carbon and chlorine. The molar mass of carbon is 12.011 g/mol, and the molar mass of chlorine is 35.45 g/mol.

Now determine the molar mass of #"CCl"_4"#.

#(1xx12.011 "g/mol")+(4xx35.45 "g/mol)=153.8 g/mol"#
