Your radiologist is a medical doctor who specializes in diagnosing and treating disease and injury, using medical imaging techniques such as x-rays, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET), fusion imaging, and ultrasound.
Explanation:
It is known that the molecular weight of ammonia () is as follows.
Molecular weight () = = 17
(a) Therefore, we will calculate the mass as follows.
= 8500 g
Now, formula to calculate weight of the system in N is as follows.
Weight = mass × g
=
= 83.3 N (1 = 1 N)
Hence, the weight of the system is 83.3 N.
(b) Relation between specific volume and number of moles is as follows.
Therefore, calculate the specific volume as follows.
= 12
Also,
v =
= 0.705882
Therefore, we can conclude that the value of specific volume is 12 and 0.705882 .
Solar energy and Hydro is the correct option.
<h3>Which sources provide energy nowadays?</h3>
Today's energy supply is provided by solar energy and Hydro as compared to our ancestors because our ancestors have no modern technology to obtain energy from sun and water. They get energy from burning of fossil fuels and biomass.
So we can conclude that solar energy and Hydro is the correct option.
