HELP PLEASE :( ||What is the concentration of KCl if 10 g are dissolved in enough water to make 12 L?

see explanation

Explanation:

By definition solution concentration = amount of solute/amount of solution

solution = solute + solvent

There are several ways to express concentration of solute in solution; grams/Liter, moles/Liter, pounds/gallon, grams/milliliter, etc. I'm guessing your problem is asking for either g/L or moles/L where moles/L is called a Molar Concentration.

Given 10 grams solute & 12 Liters of solution, concentration = 10g/12Liters = 0.83g/L.

If Molar concentration is needed, convert the solute mass into moles (divide by formula wt.) then apply to Molar Conc. = moles solute/Liters of solution.

Molar concentration => [KCl] = (10g/74g·mol⁻¹)/(12L) = 0.011Molar or. 0.011M.

hey

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.
