An aqueous antifreeze solution is 40.0% ethylene glycol (C2H6O2) by mass. The density of the solution is 1.05 g/cm3. Calculate the molality, molarity, and mole fraction of the ethylene glycol. molality WebAssign will check your answer for the correct number of significant figures.10.7 Correct: Your answer is correct. mol/kg molarity WebAssign will check your answer for the correct number of significant figures.6.76 Correct: Your answer is correct. mol/L mole fraction of ethylene glycol

these nuts

1. they vary with a higher number because boiling is way hotter than melting

the answer is d.) potassium

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.
