The concentration of the final solution will be 0.2886 M.
<h3>Molar concentration</h3>
50.6 g of NaCl is dissolved in 600 mL of water.
Mole of 50.6 g NaCl = 50.6/58.44 = 0.8658 mol
Molar concentration of the oiriginal solution = 0.8658/06 = 1.4431 M
25 mL of 1.4431 M of the solution is diluted up to the 125 mL mark.
m1 = 1.4431, v1 = 25 ml, v2 = 125 mL
m2 = m1v1/v2 = 1.4431 x 25/125 = 0.2886 M
The concentration of the final solution will be 0.2886 M

#SPJ1
Total in pot=28 L
400 mL in each bowl
16 bowls filled
1000mL=1L
16 bowls(400mL/1 bowl)=6400mL
6400mL(1L/1000mL)=6.4L
28L-6.4L=21.6 L
The answer is .0004704. i hope that helped.
Answer:
C. is less than 0
Explanation:
The Gibbs free energy (G) of a system is defined as the energy that is used for the work done. The change in Gibbs free energy during a reaction shows the spontaneity and energetics of the reactions.
A reaction will be spontaneous if the change in Gibbs free energy will be negative or less than 0. Reactions with positive Gibbs free energy are non-spontaneous.
Hence, the correct answer is "C. is less than 0".
