Answer:
The molar mass (or the atomic mass on the periodic table) is equal to one (1) mole of that specific element.
With compounds, just add up the molar mass of each element in the compound. Make sure you have the right number of each element as well (see the subscripts attached to the element symbol)
***Diatomic elements (when by themselves) are ALWAYS is pairs
Example:
H₂O = 2 hydrogen + 1 Oxygen
H has a molar mass of 1.008
O has a molar mass of 15.999
since we have 2 hydrogen, we multiply it's molar mass by 2
now we add the masses
1 mole of H₂O = 18.015 g of H₂O

Answer: What substances dissolve in ocean water.
This is the only question that can be answered through scientific investigation because it is the only question that can be tested. The other questions cannot be answered through scientific investigation because they based on opinions which are more abstract.
