A 1.00 g sample of a metal X (that is known to form X^2+ ions) was added to 0.100 L of 0.500 M H2SO4. After all the metal had reacted, the remaining acid required 0.0334 L of 0.500 M NaOH solution for neutralization. Write the molecular, total ionic, and net ionic equations for the reaction and calculate the molar mass of the metal and identify the element.
