Answer:Explanation:i have given answer please give me brainlistThe number of neutrons is equal to the difference in the mass number and atomic number.

It is equal to 14−6=8.

(a) The number of neutrons present in 7 mg of C-14:

=14

7×10−3

×6.02×1023

×8

=2.408×1021

neutrons

(b) Total mass of neutrons in 7 mg of C-14:=2.4088×1021

×1.675×10−27

=4.035×10−6

kg.
