Hint: Acetone is a ketone and its molecular formula is . It means that in one molecule of acetone, the number of carbon atoms present are 3. The formula, will be used to calculate the mass of the acetone and the mass will be converted to moles.
Complete step by step answer:
Given,
Volume of acetone
Density of acetone
We know
Therefore,
Mass of acetone
We know that
Number of moles
Molar mass of acetone
Number of moles of acetone
Number of moles of Carbon atoms
So, the number of carbon atoms present in of acetone is 0.124.
Therefore, the correct answer is option (C).
