Molecular Formula Of Serotonin Through Mass Percent Of Its Constituents

Serotonin is a compound that conducts nerve impulses in the brain. It contains 68.2 mass percent of carbon (C); 6.86 mass percent of hydrogen (H); 15.9 mass percent of nitrogen (N); and 9.08 mass percent of oxygen (O). Its molar mass is 176 g/mol. Determine its molecular formula.

**The strings**:
S_{7}P_{2}A_{22} (identity - chemical).
**The math**:

Pj Problem of Interest is of type *identity* (chemical).

Amount of carbon in grams = 176(0.682 = 120 g

Amount of hydrogen in grams = 176(0.0686) = 12 g

Amount of nitrogen in grams = 176(0.159) = 28 g

Amount of oxygen in grams = 176(0.0908) = 16 g

Moles of carbon = 120/12 = 10 moles

Moles of hydrogen = 12/1 = 12 moles

Moles of nitrogen =28/14 = 2 moles

Moles of oxygen = 16/16 = 1 mole.

So, empirical formula = C_{10}H_{12}N_{2}O

Empirical mass = molar mass

So empirical formula = molecular formula

So, molecular formula = C_{10}H_{12}N_{2}O.

Math

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
