Oxygen is gas. It has 2 O atoms. Atomic mass of 1 O atom is 16 amu. So molecular mass of O2 = 2 x 16 = 32 amu.
Now, mass of 6.023 x 10 ^23 = 32 amu.
Therefore mass of 3.01 x 10^23 = 32 x 3.01 x 10^23 / 6.023 x 10 ^23 = 15.99
= ~16 gm
Nuclear fission is the breakup of an atom and Nulcear fusion is the combination of two (or more, but almost always two) atoms to form a new atom.
Answer: D
Explanation: When neutrons are required for transmutation reactions, they are usually ... Plutonium is now mostly formed in nuclear reactors as a byproduct during the decay ... If this process continues, a nuclear chain reaction occurs.
