Calculate the number of carbon atoms in

Question

0.75 L of acetone (CH3COCH3). (density
= 1.3 g/mL and boiling point = 48.5 degrees Celsius)

Answer 1

Use the density to calculate mass acetone (mass = volume x density), convert mass to moles (moles = grams/molar mass). Remember there are 6.022E23 molecules in a mole (to calculate number of acetone molecules). Finally, there are three C atoms per molecule acetone.

Answer 2

3.03 x 10^25
