Answer:
C. The lowest whole-number ratio of atoms in a molecule.
Explanation:
Hello there!
In this case, according to the definition of the empirical and the molecular equations, it is possible for us to consider the following example of molecular formula, C4H10, whose empirical formula is C2H5.
In such a way, it is possible for us to say that the empirical formula gives C. The lowest whole-number ratio of atoms in a molecule, as it is the result of the simplification of the molecular formula when possible.
Regards!
You need to calculate the atomic weight of that element.
number of moles = mass / atomic weight
atomic weight = mass / number of moles
atomic weight = 209.1 / 3 = 69.7 g/mol
The element produced will be gallium, Ga.

Answer:
The specific heat capacity of a metal is 1.31 J/g°C = C
Explanation:
A classical excersise of calorimetry to apply this formula:
Q = m . C . ΔT
177.5 J = 15 g . C (34°C - 25°C)
177.5 J = 15g . 9°C . C
177.5 J /15g . 9°C = C
1.31 J/g°C = C
