Which solution has the greatest osmolarity?
0.6 M NaCl
0.10 M KNO3
0.35 M AlCl3
0.2 M CaBr2
0.14 M KF

Explanation:

Osmolarity is the number of moles of particles that count to calculate the osmotic pressure, in one liter of solution.

In ionic compounds, your first calculate the molarity and then multiply it by the factor to calculate the number of particles product of the dissociation.

The factor is the number of ions produced per mole of compound.

Assuming 100% dissociation for the given solutions, the calculations are:

Solution                 Ionization     Factor            Osmolarity

0.6 M NaCl             Na⁺ + Cl⁻          2                 0.6 × 2 = 1.2          

0.10 M KNO₃           K⁺ + NO₃⁻        2                 0.10 × 2 = 0.20

0.35 M AlCl₃           Al⁺ + 3Cl⁻         4                 0.35 × 4 = 1.4

0.2 M CaBr₂           Ca²⁺ + 2Br⁻      3                  0.2 × 3 = 0.6

0.14 M KF                K⁺ + F⁻             2                  0.14 × 2 = 0.28

c, liquids evaporate, creating a gas

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.
