Question

the chemical formula for acetone is: (ch3)2co. calculate the molar mass of acetone. round your answer to 2 decimal places. g·mol−1

Explanation:

Step1: Identify the atoms and their counts

Acetone ($(CH_3)_2CO$) has 3 carbon (C) atoms, 6 hydrogen (H) atoms and 1 oxygen (O) atom.

Step2: Find the molar - mass of each atom

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

Step3: Calculate the molar mass of acetone

$M=(3\times12.01)+(6\times1.01)+(1\times16.00)$
$M = 36.03+6.06 + 16.00$
$M=58.09$ g/mol

Answer:

58.09 g/mol
