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 gHave a nice day!
option A Hydrogen will have the greatest rate of effusion beacuse it has the least mass among all
