How many atoms are there in 1 cm3 of iron?
The density of iron, Fe, at room temperature is 7.874 g/cm3. So 1cm3 of iron has a mass of 7.874g. 1 mole iron = 55.845g Fe = 6.022 x 1023 atoms Fe. 7.874g Fe x 6.022 x 1023 atoms Fe/55.845g Fe = 8.491 x 1022 atoms Fe
How many iron atoms are present in a 23.0 g iron block?
To determine the number of iron atoms in a 23.0 g iron block, you would first calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of iron to atoms.
Which one has more atoms 10 g of Al or 10 g of Fe?
use the following formula to determine number of moles number of moles = mass given/molar mass (mass on periodic table) one mole = 6.02x10^23 particles (molecules or atoms depending on substance) hence whichever mass has the greatest number of moles has the more atoms
How many moles of iron is 5.98x1024 atoms of iron?
To find the number of moles, you need to divide the number of atoms by Avogadro's number, which is about 6.022 x 10^23 atoms/mol. So, 5.98 x 10^24 atoms of iron would be approximately 9.93 moles of iron.
How many atoms in 1g H2?
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms of hydrogen gas =========================
How many moles of iron correspond to 9.003 x 1023 atoms of iron?

How many atoms in 10 mg of iron?
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
How many atoms are in 10g of nitrogen?
10 grams nitrogen (1 mole N/14.01 grams)(6.022 X 1023/1 mole N) = 4.3 X 1023 atoms of nitrogen ======================
How many moles on 738 grams or iron and how many atoms?
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
How many atoms does iron filings have?
It depends on the mass of iron. 1 mole Fe = 55.845g = 6.022 x 1023 atoms Fe
How many iron atoms are present in 55.845grams of Iron?
Amount of Fe = 55.845/55.845 = 1mol There is 1 mol of Fe in a 55.845g sample. 1 mol of Fe contains 6.02 x 1023 atoms (avogadro constant). Therefore there are 6.02 x 1023 atoms in 55.845g of iron.
How many atoms are in 5.0 mole of Fe?
Fe, or iron, has a molar mass of 55.845 grams per mole. This means that 0.2 moles is equal to 11.2 grams of iron.
How many Sn atoms are there in a 86.0 gram sample of Sn?
86.0 grams Sn (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn)= 4.36 X 1023 atoms of tin=================
