The molecular weight of NaCl is 58.44 g/mol.
0.575 mol * 58.44 g/mol = 33.6 grams of NaCl
No. The number of a protons is not equal to it's atomic weight, instead it is equal to the 'atomic number'
2 and 2 and 3 hope that helped
The chemical formula for carbon and chlorine is CCl4 (carbon tetrachloride).
In <span>c2h4o2 there are
2 atoms of carbon
4 atoms of hydrogen
2 atoms of oxygen
Hydrogen atomic masses is 1 which was very low so 4 of them would still be the lowest mass percent. Then we have carbon and oxygen which both have 2 atoms. Oxygen atomic mass is more than carbon atomic mass, so oxygen should contribute more mass percent composition. The sequence from higher mass percent composition should be:
1. Oxygen
2. Carbon
3. Hydrogen</span>
