In order to obtain the empirical formula, first divide each
element by its molar mass which can be found in the periodic table. The answer
in the first step would be the number of moles of each element. Then divide
each element with the lowest number of moles obtained in the first step in this
case Phosphorus had the lowest number of moles. Then round it up to the nearest
whole number. The empirical formula then is Phosphorus pentafluoride or PF5.
sodium element is likely to have the highest thermal conductivity
Answer: Water displacement
Explanation:
When you put an irregularly shaped object in a graduated cylinder, the water level rises. Subtract the original number of ml from the number of ml it was displaced, and you get its volume.
Answer: They are arranged by atomic number.
