Answer:

8, 53.5

Explanation:

  • Half reactions for oxidation and reduction
  • Equivalent mass is calculated by dividing molecular mass by the number of acquired or lost electrons.
  • O.N. of N is equal to 2 in N2H4 and changes to 0 in N2
  • In ICI, the iodine O.N. decreases from +5 to +1.
  • Eq mass of N2H4 = 32/4 = 8
  • Eq mass of IO3- = 214/4 = 53.5
  • The mole is a unit of measurement that is comparable to well-known quantities like pair, dozen, bulk, etc. It offers a precise count of atoms or molecules in a large sample of materials.
  • For covalent compounds, the formula mass may be appropriately referred to as a molecular mass because it indicates the numbers and kinds of atoms that make up a single molecule of the material.
