The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Answer : The mass of the helium in the blimp is, 1.1216 Kg

Solution : Given,

Volume of helium in the blimp =

conversion :

Density of helium in the blimp =

Formula used :

Now put all the given values in this formula, we get the mass of helium in the blimp.

Therefore, the mass of the helium in the blimp is, 1.1216 Kg

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
