1 mole manganese = 54.938049g
1 mole Mn atoms = 6.022 x 1023 atoms
Convert atoms Mn to moles Mn.
1.02 x 1024 atoms Mn x 1mol/6.022 x 1023 atoms = 1.69mol Mn
Convert moles Mn to mass in grams Mn.
1.69mol Mn x 54.938049g/mol = 92.8g
1E 24/6.02 E23 atoms/mole * 54.9 g/mole = 91.2592 g

2.11x10^24 atoms... Divide by Avogadro's Constant (6.02x10^23 particles/mole) Gives you moles of copper... Multiply by the molar mass of copper. (?? g/mol) Gives you grams of copper...
Fairly heavy! 1.14 X 1024 atoms of iodine ( 1 mole I/6.022 X 1023)(126.9 grams/1 mole I) = 240 grams of iodine -------------------------------
7.21 X 10^24 atoms phosphorous (1 mole P/6.022 X 10^23)(30.97 grams/1 mole P) = 371 grams of phosphorous
To convert from atomic weight to grams, multiply by 1.6605402e-24. For instance, the atomic weight of the most common isotope of Oxygen is 15.9994. In grams, that would be 15.9994 * 1.6605402e-24 = 2.656764688e-23 g.
72.0 grams Carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C) = 3.61 X 10^24 atoms of carbon
I think you meant 3.09x10^24 atoms of sulfur. 3.09x10^24 atoms * (1 mol / 6.02x10^32 atoms) * (32 g / 1mol) = 165 grams
2.11x10^24 atoms... Divide by Avogadro's Constant (6.02x10^23 particles/mole) Gives you moles of copper... Multiply by the molar mass of copper. (?? g/mol) Gives you grams of copper...
13.2 atomic mass units = 2.1919113 × 10-23 grams. (1 atomic mass unit = 1.66053886 × 10-24 grams).
Fairly heavy! 1.14 X 1024 atoms of iodine ( 1 mole I/6.022 X 1023)(126.9 grams/1 mole I) = 240 grams of iodine -------------------------------
3,09x10e24 atoms of sulfur in grams is equal to 164,65 g.
7.21 X 10^24 atoms phosphorous (1 mole P/6.022 X 10^23)(30.97 grams/1 mole P) = 371 grams of phosphorous

Divide by Molar mass and multiply by Avagadro constant 3.657*6.022*10^23=2.213*10^24
Yes, they have a mass of 1.67*10-24 grams
To convert from atomic weight to grams, multiply by 1.6605402e-24. For instance, the atomic weight of the most common isotope of Oxygen is 15.9994. In grams, that would be 15.9994 * 1.6605402e-24 = 2.656764688e-23 g.
it is exactly 238.02891 u ± 0.00003 u or in other words you can write it as 395,256.10-24 grams
