Asolution is prepared by dissolving 23.7 g of cacl2 in 375 g of water. the density of the resulting solution is 1.05 g/ml. the concentration of cacl2 in this solution is molar.

Concentration of calcium chloride solution is 0.5623 molar.

Explanation:

Density of the solution = 1.05 g/mL

Volume of the solution = V

Mass of the solution = Mass of solute +Mass of solvent

=  23.7 g + 375 g = 398.7 g

Moles of solute that id calcium chloride =

Concentration=

Concentration of calcium chloride solution is;

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.
