percentage error = error x 100 / correct value
= (2.73 - 2.70) x100 / 2.70
= 1.11 %
The element is Aluminium whose density is 2.702 grams / cc
Boiling point of Aluminium = 2519⁰C .
Explanation:
The given data is as follows.
= 225.5 mL,
= 45.00 mL
= 0.09988 M,
= ?
Therefore, formula to calculate final concentration will be as follows.
= 
Putting the given values into the above formula as follows.
= 
= 
= 0.5 M
Thus, we can conclude that the final concentration of the given solution is 0.5 M.
Answer:
