To determine the amount of a certain element in a compound, we use the ratio of the elements from the compound. We calculate is follows:
45.0 g CCl4 ( 1 mol CCl4 / 153.82 g CCl4 ) ( 1 mol C / 1 mol CCl4 ) ( 12.01 g C / 1 mol C ) = 3.5135 g carbon present
Hope this answers the question. Have a nice day.

A common clasiffication of the chemical reactions is as combination (or synthesis), decomposiion, single replacement and double replacement. Knowing the reactants and products you can tell to which one of those four classifications a reaction pertains. When two reactants combine into a single product, it is a combination (syntheisis) reaction. When a single reactant yields two or more products, it is a decomposition reaction. When the cation of a single element, replaces the cation in a compound, it is a single replacement. When the cations of two different reactants exchange and end combined with the anions of the others compounds, it is a double replacement reaction.
<em>Answer:</em>
Symbol = I
<em>Explanation:</em>
<em>Isotopes</em> are those substances which have same atomic number (Numbers of protons) and different masses (Number of proton + numbers of neutrons).
- Iodine also have many isotopes like
<em>Iodine-125</em> that contain 53 protons, 72 neutrons.
<em>Iodine-128</em> that contain 53 protons, 75 neutrons.
<em>Iodine-129 </em> that contain 53 protons, 76 neutrons.
<em>Iodine-131</em> that contain 53 protons, 78 neutrons.
<em>Summary:</em>
- Here the Iodine-131 is correct answer of this question.
