​

Answer 1

Answer:

d

Explanation:

hope u know lol ..........

Answer 2

Answer:

The correct answer is (b) mass of c-12 atom is 12u.

Explaination:

a) Mass of 1 hydrogen atom is not equal to 12u because mass of 1hydrogen atom is 1u.

b) u or Atomic mass unit (amu) is defined as 1/12th of the mass of an, neutral atom of carbon-12 isotope, which is taken as the reference standard. The atomic mass unit is used to describe the mass of a single atom or molecule.

So, the mass of a carbon-12 atom is equal to 12u and mass of 1u is described as 1/12th mass of 12-C carbon isotope.

(c) Mass of 0-16 atom is not equal to 12u, it is equal to 16u.

(d) 1/12 of mass of c-12 is equal to 1u, not 12u.

Isotopes

Isotopes are the when relative elements possesses same no. Of protons or electrons that give rise to same atomic no. but these elements have different atomic mass that is sum of protons and neutrons.
