How many acetone molecules are in a bottle of acetone with a volume of 445 mL ? (density of acetone = 0.788 g/cm3).
Mkey [24]
<h2>Hello!</h2>

The answer is: 3.63x10^{24}particles

<h2>Why?</h2>

First, we need to calculate the molecular weight of the acetone (CH3COCH3)

So,

C=12.011g/mol\\O=15.99g/mol\\H=1.008g/mol

Then,

CH3COCH3=12.011+(1.008)*3+12.011+15.999+12.011+(1.008)*3=58.08g/mol

Second, we need to calculate the mass of the acetone in the bottle

We need to remember that 1cm^{3}=1mL

So,

445cm^{3}*\frac{0.788g}{cm^{3}}=350.66g

Third, we need to calculate the number of moles:

350.66g*\frac{1mol}{58.08g}=6.03moles

Fourth, we need to calculate the number of atoms:

Remember, 1 mol=6.022x10^{23}particles

Therefore,

6.03moles*\frac{6.022x10^{23}particles }{1mol}=3.63x10^{24}particles

Have a nice day!
