Explanation:
Detailed explanation-1: -Note: The percent creation of NaOH, otherwise called sodium hydroxide, is 57.48 percent sodium, 40% oxygen, and 2.52 percent hydrogen.
Detailed explanation-2: -We know that masks of a compound is given as molar mass into a number of moles. The Mueller moss is 40 for sodium hydroxide into more salsa 2.5. On solving, we get this as 100 good on. So the mass of 2.5 moles of a new edge is 100 grand.
Detailed explanation-3: -The percent composition of NaOH, also known as sodium hydroxide, is 57.48 percent sodium, 40 percent oxygen, and 2.52 percent hydrogen.
Detailed explanation-4: -Therefore, the molarity of 2% W/V NaOH solution is equal to 0.5M.
