1) Determine the empirical formula of each of the followingcompounds if a sample contains (a) 0.104 mol K, 0.052 mol C, and0.156 mol O; (b) 5.28 g Sn and 3.37 g F; (c) 87.5% N and 12.5% H bymass.

2) Determine the empirical and molecular formulas of each of thefollowing substances:
(a) Ibuprofen, a headache remedy, contains 75.69% C, 8.80% H, and15.51% O by mass, and has a molar mass of 206 g/mol.

3) Nicotin, a component of tobacco, is composed of C, H, and N. A5.250-mg sample of nicotine was combusted, proucing 14.242 mg ofCO2 and 4.083 mg of H2O. What is the empirical formula fornicotine? if nicotine has a molar mass of 160 + 5 g/mol, or 160 - 5g/mol, what is its molecular formula?

Determine the empirical and molecular formulas of each of the following substances:
(a) Ibuprofen, a headache remedy, contains 75.69% C, 8.80% H, and 15.51% O by mass, and has a molar mass of 206 g/mol.
(b) Cadaverine, a foul-smelling substance produced by the action of bacteria on meat, contains 58.55% C, 13.81% H, and 27.40% N by mass; its molar mass is 102.2 g/mol.
(c) Epinephrine (adrenaline), a hormone secreted into the bloodstream in times of danger or stress, contains 59.0% C, 7.1% H, 26.2% O, and 7.7% N by mass; its MW is about 180 amu.

Empirial formula of ibuprofene is calculated by multiplying obtained ratio with 2, and the result is C13H18O2. The sum of atomic mass of C13H18O2 is 206 g/mol. Molecular formula is the same as empirical.

Empirical formula of cadaverine, C5H14N2 is obtained by multiplying the moles of each atom with 2 in order to obtain the whole numbers. The weight of empirical formula is 102 g/mol, so it is at the same time the molecular formula.

c) 59.0% C, 7.1% H, 26.2% O, and 7.7% N

Empirical formula of adrenaline is C9H13NO3, and its mass is 183 g/mol. Since MW of hormone is about 180, molecular formula is the same as empirical formula.
