Answer:
1)The molecular formula for a compound
2)The molar mass of a compound tells you the mass of 1 mole of that substance. In other words, it tells you the number of grams per mole of a compound. The units for molar mass are, therefore, grams/mole.
3)Through this experiment, Lavoisier proved that water was not an element, but a compound made of hydrogen and oxygen, with a weight percentage of 15% and 85%, respectively. We now know that the correct percentage should be 11% for hydrogen and 89% for oxygen.
4)C6H12O6
5)The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 x 1023 elementary entities.
