Answer:


= 3.105x10^(24)molecules\ acetone

Step-by-step explanation:

Hello!

In this case, given the volume of acetone, it is possible to compute the mass and next the moles via its molar mass (58.08 g/mol) as shown below:


n_(acetone)=380mL*(0.788g)/(1mL) *(1mol)/(58.08 g) \\\\n_(acetone)=5.16mol

Then, via the Avogadro's number it is possible to compute the acetone molecules as follows:


=5.16mol*(6.022x10^(23)molecules)/(1mol)\\\\= 3.105x10^(24)molecules\ acetone

Best regards!
