The fact that matter inundates the universe has made the study of matter an unavoidable topic. As such, we can not really be able to point something that is of made up of matter. There can be no such thing!
As long as a thing does exist in the material universe, that thing is made up of matter. Look at yourself for example, matter is spread all across your body. The same occurs in the bodies of every other living thing.
The nonliving things are not also left out as they are equally composed of diverse kinds of matter that exists in the universe.

(OH)=3.72 x 10^-6 mol/L
The Options are as follow,
<span>a.
it has 13 protons c. it has 13 neutrons </span>
<span>b.
it has 13 electrons d. it
has 7 neutrons</span>
Answer:
Option-d is the correct answer.
Explanation:
As we know that C-13 has a atomic mass of 13. Also, atomic mass is given as,
<span> Atomic Mass = # of Protons + # of Neutrons --- (1)</span>
Since;
Atomic Mass = 13
And,
# of protons = 6 (as number of protons = atomic number)
Putting values in equation 1,
13 = 6 - # of Neutrons
Solving for Number of Neutrons,
# of Neutrons = 13 - 6
# of Neutrons = 7
