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!
