Transition metals are a large group of elements that include some of the most common metals such as copper and chromium. They also include elements that can create a magnetic field, such as nickel and iron. Transition metals are great conductors of electricity because the outer electrons are capable of flowing easily.

  • CH4N, 90g, C3H12N3.

<em>Explanation:</em>

                    <em>Option C:</em>

  • The molecular formula is C3H12N3.
  • If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
  • The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g

                <em>Option A :</em>

  • In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.
