Asample has a mass of 35.4g and a volume of 36.82ml. what is the density of the sample

The density of the sample is 0.96 g/mL.

Density is found by dividing the mass of an object by its volume.

D=m÷v

D=35.4 g÷36.82 mL

D=0.96 g/mL

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.  

it is thermal conduction according to apex : )
