A chemist dissolved crystals of an unknown substance into water at room temps. He found 33 g of the substance can be dissolved into 100 mL of water. What property of the unknown substance was the chemist most likely investigating?

the answer is true.

the answer is 0.42 is that is an option. this question provides no info

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.
