Question

ethanol is the common name for a compound used as an antiseptic and a disinfectant. it has the chemical formula $c_2h_6o$. what is the mass of one mole of ethanol?
? g/mol

Explanation:

Step1: Find atomic masses

Carbon (C): \(12.01\) g/mol, Hydrogen (H): \(1.008\) g/mol, Oxygen (O): \(16.00\) g/mol.

Step2: Calculate for each element

For C: \(2\times12.01 = 24.02\) g/mol.
For H: \(6\times1.008 = 6.048\) g/mol.
For O: \(1\times16.00 = 16.00\) g/mol.

Step3: Sum the masses

Molar mass = \(24.02 + 6.048 + 16.00 = 46.068\) g/mol.

Answer:

\(46.07\) (or \(46.068\))
