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

Thanks. Would you be saying that 500 (grams) divided by 885 (molecular mass) equals 0.5649717? I am confused with avegardos number and when i use it in the equation?

To calculate the number of moles of olive oil molecules in 500g of olive oil, you need to use the molar mass of triolein and the given mass of olive oil. Here's how you can calculate it:

1. Begin by determining the molar mass of triolein. Given that its molar mass is 885 g/mol, this means that one mole of triolein weighs 885 grams.

2. Next, calculate the number of moles of olive oil by using the formula:

Moles = Mass / Molar mass

Given that the mass of olive oil is 500g, divide it by the molar mass of triolein to calculate the number of moles:

Moles = 500g / 885 g/mol

3. Solve the equation using a calculator:

Moles ≈ 0.565 moles

Therefore, you have approximately 0.565 moles of olive oil molecules in 500g of olive oil.
