The empirical formula should be first determined. Empirical formula is the simplest ratio of whole numbers of components in a compound.
for 100 g of the compound
C H Cl
mass 46.47 g 7.80 g 45.72 g
number of moles 46.47 g/12 g/mol 7.80 g/1 g/mol 45.72 g/35.5 g/mol
= 3.87 mol = 7.80 mol = 1.29 mol
divide all by the least number of moles
3.87/1.29 = 3 7.80/1.29 = 6.04 1.29/1.29 = 1
when they are all rounded off to the nearest whole number
number of atoms are as follows
C - 3
H - 6
Cl - 1
the empirical formula is C₃H₆Cl
molecular formula is the actual number of components in the compound
molar mass = 155.06 g/mol
we have to find the mass of the empirical unit
mass of C₃H₆Cl - (12 g/mol x 3) + (1 g/mol x 6) + (35.5 g/mol x 1) = 77.5
we have to then find how many empirical units are in the molecular formula
number of units = molecular mass / empirical unit mass
= 155.06 g/mol / 77.5 = 2.00
there are 2 empirical units
molecular formula = 2 (C₃H₆Cl)
molecular formula - C₆H₁₂Cl₂

Answer:
Likely an issue with the mitral valve.
Explanation:
If I read this correctly, you are likely referring to mitral regurgitation, which is a process where your mitral value does not close tightly enough to stop the blood to flow into left atrium.
Normally, when the left ventricle is full, the mitral valve shuts to prevent blood blood from flowing backward into the atrium while the ventricle contracts, and this allows for blood to go to aorta and to body. According to question since the process is reversed, I am gonna go out on a limb and say mitral valve is likely the structure affected by this since and how I came to conclusion is all the explaintion I did earlier.
Answer:
Hydrogen
Explanation:
By definition a difference in pH is a difference in amount of hydrogen ions
