Question

What is the mass (in g) of 0. 935 mol of acetone CH3COCH3 the molar mass of acetone is 58. 08 g∙mol^–1.

Answer 1

Given Chemical Formula of the Acetone = CH₃COCH₃

Mass of the C = 12 g.

Mass of the H = 1 g.

Mass of the O = 16 g.

Molecular mass is the sum of the masses of the elements present in 1 molecule of the compounds.

Molecular mass of the Acetone = 12 + 1 × 3 + 12 + 16 + 12 + 1 × 3

= 12 + 3 + 12 + 16 + 12 + 3

= 36 + 6 + 16

= 58 g/mole.

Hence, the molar mass of the acetone is 58 g/mole.

Molecular Mass

The mass of a given molecule is its molecular mass (m), which is expressed in daltons (Da or u).  Because they contain various isotopes of an element, multiple molecules of the same substance can have distinct molecular weights. According to IUPAC, the related quantity relative to molecular mass is a unitless comparison between the mass of a molecule and the unified atomic mass unit (also called the dalton). The molar mass is unrelated to, but distinct from, the molecular mass and relative molecular mass. The molar mass, which is stated in g/mol, is defined as the mass of a specific material divided by the amount of a substance. When addressing macroscopic issues, the molar mass is typically the most relevant figure (weigh-able).
