∙ 10y ago
Amount of Fe = (2.71x1024)/(6.02x1023) = 4.50mol
The Atomic Mass of Fe is 55.8
Mass of Fe = 4.50 x 55.8 = 251g

How many atoms are there in 34 grams of lithium?
Li atomic mass= 6.941g/mol= 4.9 moles of Li1.00 mol = 6.02 x 1023 atoms4.9 mol Li = 2.95 x 1024 atoms= 3.0 x 1024 atoms
How many atoms are in 147 g of calcium?
Quite a few! 147 grams calcium (1 mole Ca/40.08 grams)(6.022 X 1023/1 mole Ca) = 2.21 X 1024 atoms of calcium ----------------------------------------
How many atoms are in 115 grams of Calcium?
Avogadro's Number, 6.022 x 1023 gives the number of atoms in one mole. Calcium has an average atomic weight of 40.08 gmol-1 So one mole weighs 40.08 grams. 115 grams of Calcium will have (6.022 x 1023 / 40.08)*115 = 1.73 x 1024 atoms.
How many atoms of tin are in 118.7 g of tin?
118.7 is close to the 118.96 grams per mole (mass) of tin. So we can call that one mole. 1 mole is equal to 6.022x10^23 (avogadro's number which is the number of atoms per mole of an element).
How many atoms are in a 2.5 mole sample of calcium?
450.3915Calcium Carbonate (CaCO3) has a molar mass of 100.087 g/mol.4.5 mol * 100.087 g/mol = 450.3915 (because the mol's cancel leaving you with grams)
How many atoms are in a 341g sample of scandium?
341 grams scandium (1 mole Sc/44.96 grams)(6.022 X 1023/1 mole Sc) = 4.57 X 1024 atoms of scandium =====================
How many moles are there in a sample containing 2.4081024 atoms of carbon?
1 mole C = 6.022 x 1023 atoms 2.408 x 1024 atoms C x 1mol/6.022 x 1023 atoms = 3.999 moles C
How many grams are there in 2.3x10 to the 24th power atoms of silver?
2.3 X 1024 atoms / 6.022 X 1023 atoms/mole X 107.87 gm/mole of silver = 412 grams
How many atoms are in 131 grams of calcium?
There are 3.275 moles of calcium in 131 grams as relative atomic mass of calcium is 40. Therefore there are 1.972 x 1024 atoms.
How many grams are in a sample of sulphur trioxide that has 1.88 x 1024 molecules?
1.88 X 1024 molecules SO3 (1 mole SO3/6.022 X 1023)(80.07 grams/1 mole SO3) = 250 grams sulfur trioxide ===================
How many atoms are there in 34 grams of lithium?
Li atomic mass= 6.941g/mol= 4.9 moles of Li1.00 mol = 6.02 x 1023 atoms4.9 mol Li = 2.95 x 1024 atoms= 3.0 x 1024 atoms
How many carbon atoms are there in 31.8 grams of carbon?
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
How many atoms are there in 170 grams of ammonia?
Quite a few! 170 grams ammonia (1 mole NH3/17.034 grams)(6.022 X 1023/1 mole NH3) = 6.01 X 1024 atoms of ammonia ========================
How many atoms are in 55.2 grams Li?
The atomic weight of Li is 6.941 g/mol The mass of the sample is 55.2 g This means that: 55.2/6.941=7.95 moles (rounded number) Multiplying this with Avogadro's number (6.022*1023) 7.95*6.022*1023=4.79*1024 atoms. There you have your answer.
What is the mass of 1.14x10 24 atoms of iodine?
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 -------------------------------
How many atoms are in 64 g S?
64 grams sulfur (1 mole S/32.07 grams)(6.022 X 1023/1 mole S) = 1.2 X 1024 atoms of sulfur ====================
How many atoms are in each elemental sample 4.0mol Cu?
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
