one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol. This means that every mole of sulfuric acid has a mass of 98.0795 g. Since you're dealing with one mole of sulfuric acid, it follows that you will also be dealing with two moles of hydrogen.

Answer:
X is sodium hydroxide (caustic soda, NaOH)
y is sodium (Na)
Explanation:
The process of industrial electrolysis of sodium chloride solution by which chlorine and sodium hydroxide (caustic soda) can be produced is known as the chlor-alkali process as follows;
2NaCl + 2H₂O → Cl₂ + H₂ + 2NaOH
Given that the compound X is formed from a element y which is in the form of a pellet, we have;
The element in the above reaction that can exist as pellet is the silver white metallic sodium pellet
Therefore, the compound X is NaOH and the element y is sodium, Na.
