How to Calculate the Number of Carbon Atoms in Acetone?
Understanding the Problem
Acetone (CH3COCH3) is a common organic compound used as a solvent. To calculate the number of carbon atoms in 15.6 kg of acetone, we need to use the given information about the density of acetone and its chemical formula.
Given Data
Mass of acetone = 15.6 kg
Density of acetone = 1.30 g/ml
Chemical formula of acetone = CH3COCH3
Conversion of Units
Since the density is given in grams per milliliter, we need to convert the mass of acetone from kilograms to grams.
1 kg = 1000 g
Therefore, 15.6 kg = 15,600 g
Calculating the Molar Mass of Acetone
The molar mass of acetone (CH3COCH3) can be calculated by adding the atomic masses of carbon, hydrogen, and oxygen present in the chemical formula.
Carbon (C) atomic mass = 12.01 g/mol
Hydrogen (H) atomic mass = 1.01 g/mol
Oxygen (O) atomic mass = 16.00 g/mol
Molar mass of acetone = (3 x 12.01) + (6 x 1.01) + (1 x 16.00) = 58.08 g/mol
Calculating the Number of Moles
Number of moles of acetone = Mass / Molar Mass
Number of moles of acetone = 15,600 g / 58.08 g/mol = 268.91 mol
Finding the Number of Carbon Atoms
Since there are 2 carbon atoms in a molecule of acetone, we can calculate the number of carbon atoms as follows:
Number of carbon atoms = 2 x Number of moles
Number of carbon atoms = 2 x 268.91 = 537.82
Final Answer
There are approximately 537.82 carbon atoms in 15.6 kg of acetone.
