Answer : The molecular formula of the compound will be, [tex]C_{12}H_{42}[/tex]
Explanation :
Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.
Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
[tex]n=\frac{\text{molecular mass}}{\text{empirical mass}}[/tex]
As we are given that the empirical formula of a compound is [tex]C_2H_7[/tex] and the molar mass of compound is, 186.5 gram/mol.
The empirical mass of [tex]C_2H_7[/tex] = 2(12) + 7(1) = 31 g/eq
[tex]n=\frac{\text{molecular mass}}{\text{empirical mass}}[/tex]
[tex]n=\frac{186.5}{31}=6[/tex]
Molecular formula = [tex](C_2H_7)_n=(C_2H_7)_6=C_{12}H_{42}[/tex]
Thus, the molecular formula of the compound will be, [tex]C_{12}H_{42}[/tex]
Answer:
The most common injury in the United States is an Ankle sprain.
Explanation:
The most common injury in the United States is an ankle sprain, which is a partial or complete rupture of the ligaments that support the ankle as a result of a fall or injured ankle while walking. Ligaments are strong tissue bands that bridge the joints and attach the bones to one another. They are in excruciating pain when damaged and require medical attention. The tight bands of tissue that keep the ankle bones together might be stretched or torn as a result of this. Swelling, pain and the limited range of motion are all symptoms of a sprained ankle.
