How many grams are in 4.5 moles of mg? how do you know?

4. Molar mass of silver m Ms~=108 g/mol

Hence there are n=54*(1/108)=0.5 mols of Silver in 54 grams of Silver.

5. 6.3*(108/1)=680.4g

6. Avogadro's number : Na~=6.022×10^23.

6.0*(6.022*10^23/1)=36.132*10^23 atoms

7. Molar mass of Krypton : Mk=84 g/mol

112/84=1.33 moles of Kr

8. 1.93*10^24*(1/(6.022×10^23))=3.2 moles KF

9. Molar mass of Silicon : Ms=28 g/mol

86.2*(1/28)*(6.022×10^23/1)=18.5*10^23 atoms of silicon

10. Molar mass of Magnesium : M1=24 g/mol

4.8*10^24*(1/(6.022×10^23))*(24/1)=191 g Mg
