Beginner chemistry...mole particles..?

Question

Hey i need help with this question,i tried it but keep getting it wrong.

The particle is F2 and its 1 mole,i need to find # of molecules and # of atoms of each type
help please
and if you also help me with this one
The particle is CuNO3 and its 1 mole,i need to find # of molecules and # of atoms of each type

thank you

Answer 1

1 mole of anything is 6.02245 x 10e23 units, so one mole of diatomic fluorine has 6.02245 x 10e23 MOLECULES. Now you have 2 atoms of fluorine for each molecule, so you have 2 x 1 mole = 2 moles = 2 x (6.02245 x 10e23) = 1.20449 x 10e24 ATOMS of Fluorine.



For the second question, use the same tactic; you have 6.02245 x 10e23 molecules of CuNO3 in one mole. In each CuNO3 molecule, you have 1 copper (so you have 6.02245 x 10e23 atoms of Cu), 1 nitrogen (so you have 6.02245 x 10e23 atoms of N), and 3 Oxygens (so you have 3 x 6.02245 x 10e23 atoms of oxygen, or 1.806735 x 10e24 atoms of oxygen)

Answer 3

DE: Yep. Use this for announcing WITH WHAT or the place you do even though. working example: "watashi wa kuri o HOKU DE tabemasu" - "I consume a chestnut utilising A FORK". If the sentence involves the particle "o", then placed "___ de" between the "o" and the verb. NI: it is used for temporal place (the TIME at which you do even though). not sure approximately it getting used for places (i'm now not very complicated at eastern)... NO: think of of this as a "opposite OF" - that's like which comprise 's onto the top of even though. "watashi" = "I", "ringo" = "apple"; subsequently, "watashi no ringo" is "my apple" in spite of the shown fact that than "the apple's me". O: it is somewhat used for an excellent variety of verbs, now not purely circulation. I evaluate "desu" is the exception. "O" will must be placed in the present day in the past than the verb (in spite of the shown fact that as reported in the past than you would be waiting to placed "_____ de" between the "o" and the verb to describe how or in which you do it).
