Answer me short answer

Zepler [3.9K]

Explanation:

B. 1) Tritium is the isotope of Hydrogen (H).

2) Mass of an Electron is 9.10938356 × 10-³¹ Kg.

3) Molecular mass of Carbon dioxide (CO2)

=> Molecular mass of carbon = 12g

Molecular mass of oxygen= 16g

molecular mass of CO2 = [12 + (16 X 2)]g

= (12 + 32)g

= 44 g

4) Dalton has given its Atomic Theory in the year 1803.

5) Nucleus is discovered by

= Ernest Rutherford discovered the nucleus of the atom in 1911.

hope this helps you.
