Question

the chemical formula for diethyl sulfoxide is: (ch3ch2)2so. calculate the molar mass of diethyl sulfoxide. round your answer to 1 decimal place. g·mol−1

Explanation:

Step1: Identify the atoms and their counts

The formula is \((CH_3CH_2)_2SO\). There are 4 carbon (C) atoms, 10 hydrogen (H) atoms, 1 sulfur (S) atom and 1 oxygen (O) atom.

Step2: Find the atomic masses

The atomic mass of C is approximately 12.01 g/mol, H is approximately 1.01 g/mol, S is approximately 32.07 g/mol and O is approximately 16.00 g/mol.

Step3: Calculate the molar - mass contribution of each element

For C: \(4\times12.01 = 48.04\) g/mol. For H: \(10\times1.01=10.1\) g/mol. For S: \(1\times32.07 = 32.07\) g/mol. For O: \(1\times16.00 = 16.00\) g/mol.

Step4: Sum up the contributions

\(48.04 + 10.1+32.07 + 16.00=106.21\approx106.2\) g/mol.

Answer:

106.2 g/mol
