Answer:Hence, in 8g of Oxygen molecules, there are 3. 011 x 10²³ Oxygen atoms. In this way, how many moles are in 16 grams of oxygen? In other words, 1 mole of oxygen would contain molecules
Explanation:
F atomic number 9, mass 19
Ne atomic number 10, mass 20
Na atomic number 11, mass 23
Mg atomic number 12, mass 24
The term formula units means molecules.
Then, what you are looking for is the mass in 4.59*10^24 molecules.
The procedure involves to convert the 4.59 * 10^24 molecules into moles and use the molar mass of the sodium chloride.
1) Number of moles = 4.59 * 10^24 molecules / (6.02 * 10^23 molecules/mol) = 7.62 mol
2) Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
3) mass of NaCl = molar mass * number of moles = 58.44 g/mol * 7.62 mol = 445.31 g of NaCl
Answer: 445.31 g of NaCl.
