The empirical formula of the metal oxide would be
Mass of scandium = 0.502g
Mass of scandium + oxygen = 0.768g
Mass of oxygen = 0.768 - 0.502 = 0.266g
Mole of scandium = 0.502/44.95 = 0.011
Mole of oxygen = 0.266/16 = 0.017
Divide by the lowest:
Scandium = 0.011/0.011 = 1
Oxygen = 0.017.0.011 = 1.5
Thus, the empirical formula of the compound would be or

Answer: 0.377 moles of calcium chloride will be formed.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
As 1 mole of give = 1 mole of
Thus 0.377 moles of give =
of
Thus 0.377 moles of calcium chloride will be formed upon the complete reaction of 27.9 grams of calcium hydroxide with excess hydrochloric acid
