Answer: The concentration of the diluted solution is 0.635 M.
Explanation:
The given data is as follows.
= 12.7 M, 
= 25.0 ml = 0.025 L (as 1 ml = 0.001 L)
= ? , 
= 0.5 L
Therefore, we will calculate the molarity of the solution as follows.
= 0.635 M
Thus, we can conclude that the concentration of the diluted solution is 0.635 M.

Answer:
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

The answer is B. Hope that helped!
The balanced chemical equation for this is:
C3H8 + 5 O2
--> 3 CO2 + 4
H2O
So we can see that for every 1 mole of C3H8, 2219.9 kJ of
energy is released. Hence the total number of moles of C3H8 required is:
moles C3H8 = 2.45×10^6 kJ / (2219.9 kJ / mol)
moles C3H8 = 1103.65 mol
The molar mass of C3H8 is 44.1 g/mol, therefore the mass
is:
mass C3H8 = 1103.65 mol * 44.1 g/mol
mass C3H8 = 48,671.11 grams = 48.67 kg
