2. Olive oil is almost pure triolein (a molecule). The molar mass of triolein is 885 g/mol. How many olive oil molecules have you got in 500g of olive oil?

To find the number of olive oil molecules in 500g of olive oil, you can use the concept of moles and Avogadro's number.
First, calculate the number of moles of olive oil using the molar mass of triolein:
Molar mass of triolein = 885 g/mol
Number of moles = Mass of olive oil / Molar mass of triolein
Number of moles = 500g / 885 g/mol
Next, use Avogadro's number, which is approximately 6.022 x 10^23, to convert the number of moles into the number of molecules:
Number of molecules = Number of moles x Avogadro's number
Number of molecules = (500g / 885 g/mol) x (6.022 x 10^23)
Now, let's calculate:
Number of molecules = (500 / 885) x (6.022 x 10^23)
Number of molecules ≈ 3.410 x 10^23 olive oil molecules
Therefore, there are approximately 3.410 x 10^23 olive oil molecules in 500g of olive oil.
