Answer:
Here's a quick conversion before I answer your question, use it whenever needed.
1 moles Copper to grams = 63.546 grams. 2 moles Copper to grams = 127.092 grams. 3 moles Copper to grams = 190.638 grams. 4 moles Copper to grams = 254.184 grams. 5 moles Copper to grams = 317.73 grams. 6 moles Copper to grams = 381.276 grams. 7 moles Copper to grams = 444.822 grams.
Ok, now I'll answer your question.
Atomic masses are given in atomic mass units. One atomic mass unit is equal to one gram per mole. When you add these together for a compound, you get the molar mass of that compound. For example, silicon dioxide consists of one silicon atom and two oxygen atoms. The atomic mass of silicon is 28 grams and the atomic mass of oxygen is 16 grams.
(Hope the conversion and the answer helped) Sky
The structure is attached below.
<h3><u>Explanation:</u></h3>
Lewis dot structure was invented by Scientist Lewis which mainly focused on the distribution of electron on outermost shell around an atom in a molecule. It represented the atoms by their symbols and the Electron by dots. The bonds between the atoms are expressed by a straight line.
Around sulphur are 6 electrons on the outermost shell. In SF₆, the hybridization is sp³d². So there are 6 fluorine atoms around Sulphur with which fluorine forms 6 covalent bonds.
use the molar mass of the molecule (163.94) and then your units cancel
