5) Determine the mass in gram of 1.33 x 10^22 gram of Sb?

I need the answer for that plz help

I believe it's 2.70 grams

Explanation:

First, divide 1.33 x 10^22 by 6.022 x 10^23. 6.022 x 10^23 is Avogadro's constant of 1 mole of any atoms. After you divide, you get 2.208568582 x 10^-2 which you should round the the nearest hundredth which is 2.21 x 10^-2. Second, because of Sb or Antinomy atomic mass is 121.760, round it up to the whole number which is 122. Therefore, multiply 122 and 2.21 x 10^-2 which it'll equal to 2.6962 x 10. Finally, round it up and you'll get 2.70 grams. Hope that helps!

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
