Find the mass in grams of 2.00x10^23 molecules of f2

Hello!

To find the mass in grams of 2.00 * 10²³ molecules of F₂ you'll need to apply the Avogadro's number, which tells the number of molecules in a mol of a substance, and the Molar Mass, which tells the weight of a mole of a substance. These two quantities are used in the following conversion factor:



So, the mass of 2.00 * 10²³ molecules of F₂ is 12,51 g

Have a nice day!

You would do 1500/4 and the answer is 375
