To solve the question step by step, we will identify the metal (X), the basic salt (Y), and the gas (Z) produced when the metal reacts with cold water. We will also write the chemical reaction involved. ### Step 1: Identify the Basic Salt The basic salt Y is given as XOH. We know that the molecular mass of Y is 40 g/mol. ### Step 2: Calculate the Molecular Mass of Metal X The molecular formula of Y (XOH) can be broken down into its components: - Molecular mass of oxygen (O) = 16 g/mol ...
