What mass of NaClO2, is contained in 400 grams of water whose
molality is 0.60

Nacio, is contained in 400 grams of water whose molality ... Molality= moles of solute / mass of solvent in Kg Now molality=0.60 Mass

Explanation:

it takes on an electronical energy

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.
