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

Answer : The number of automobiles needed are, 
Explanation :
First we have to calculate the mass of blueberries.
As, 1.0 mole of blueberries contains 
blueberries
So, 0.75 grams of blueberries contains 
blueberries
Mass of blueberries = 
Now we have to calculate the number of automobiles needed.
Number of automobiles needed = 
Number of automobiles needed = 
Number of automobiles needed =
Thus, the number of automobiles needed are,
when the thermal energy is the energy contained within a system that is responsible for its temperature.
and when the thermal energy is can be determined by this formula:
q = M * C *ΔT
when q is the thermal energy
and M is the mass of water = 100 g
and C is the specific heat capacity of water = 4.18 joules/gram.°C
and T is the difference in Temperature = 50 °C
So by substitution:
∴ q = 100 g * 4.18 J/g.°C * 50
= 20900 J = 20.9 KJ
Answer:
The question is incomplete.
