What is the mass of 1 mole of MgSO 4?
1 Fe= 55.85 1 S= 32.07 4 O= 64.00 Molar mass= 151.5304
What is the maximum mass of iron metal if 50.0 grams of ironIII oxide is mixed with 50.0 grams of aluminum?
Fe2O3 + 2Al --> 2Fe + Al2O3Before:50.0g + 50.0g > 0.0g + (not important)159.69(g/mol) + 26.98(g/mol)In mol (before reaction):+0.3131 mol + 1.853 mol (excess)Reaction (used reactant > formed Fe):-0.3131 mol - 0.6262 mol > + 0.6262 mol FeRemaining (= before - used):0.0 mol Fe2O3 + 1.227 mol Al > 0.6262 mol Fe, this should be multiplied by the molar mass of Fe to get mass in grams: 0.6262 (molFe) * 55.85 (g/molFe) = 34.97 = 35.0 g Fe
Calculate the number of atom in 13.2 mol copper?
To calculate the number of atoms in 13.2 mol of copper, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply 13.2 mol by Avogadro's number to get the number of atoms: 13.2 mol * (6.022 x 10^23 atoms/mol) = 7.93 x 10^24 atoms. Therefore, there are approximately 7.93 x 10^24 atoms in 13.2 mol of copper.
How do you convert 0.25 moles gold to atoms?
1 mol = 6,022 140 857(79).10e23 atoms.0,25 mol is 1,50553521425.10e23 atoms.
How many atoms are present in 4.80 mole of Fe?
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
How many atoms are in 10g of Fe?
Molar mass of iron = 55.845g/mol (atomic weight in grams/mol) 1mol Fe atoms = 6.022 x 1023 atoms Fe 10g Fe x 1mol/55.845g x 6.022 x 1023 atoms/mol = 1.078 x 1023 atoms
Determine the number of atoms in 3.75 mol Fe?
Since a mole of a metal is generally considered to be Avogadro's Number of atoms of the metal, the answer is 3.5 times Avogadro's Number or 2.1 X 1024 atoms, to the justified number of significant digits.
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 moles of nitrogen atoms are present in 53.55 g of FeNO32?
Molar mass of Fe(NO3)2 is 55.85 + 2(14.00 + 3(16.00)) = 179.85 g/mol Therefore, number of moles of Fe(NO3)2 present is 53.55/179.85 = 0.2977 mol For each molecule of Fe(NO3)2, there are two atoms of nitrogen associated with it. Therefore, there are 0.2977*2 = 0.5954 mol of nitrogen atoms
What minimum mass of HCl in grams would you need to dissolve a 2.2 g iron bar on a padlock?
3.8 g Fe * 1 mol Fe/55.85 g Fe (molar mass) = .0680 mol Fe .0680 mol Fe * 2 mol HBr/1 mol Fe (found in formula Fe+2HBr=>FeBr2+H2)=.136 mol HBr .136 mol HBr*80.912 g HBr/1 mol HBr=11.004 g HBr (or 11 using 2 sig figs) And the mass of H2 that is produced is 0.14 g
Which has more atoms 3.0 grams of iron Fe or 2.0 grams of sulfur?
3.0 g Fe x 1 mole Fe/55.8 g = 0.054 moles Fe2.0 g S x 1 mole S/32 g = 0.063 moles STherefore there are more molecules of S than of Fe since one mole of either = 6.02x10^23 atoms.
How many atoms make 1 gram of iron?
The number of particles (atoms or molecules) in a substance is known as Avogadro's constant and is 6.02 x 1023 particles per mole. The mole is the amount of a substance that contains the same number of particles as the number of atoms in 12 grams of carbon-12. If we consider uranium 238 as the largest isotopic component of natural uranium, and as it consists of atoms not molecules, then 1 kilogram contains 1000/238 moles (1000 grams the mass, 238 the relative atomic mass), ie 4.20 moles. so the number of atoms will be 4.20 x 6.02 x 1023, or 2.529 x 1024 atoms.
How many atoms of sodium na are in 7 mol of sodium answer in units of atoms?
the constant Mole (mol): 6.02 x 10^23 are how many atoms you have per mol so the answer can be 7 mol atoms or 6.02 x 10^23 atoms per mol x 7 actual answer is 4.214 X10^24 atoms in 7 mol
What is the mass of 1 mole of MgSO 4?
1 Fe= 55.85 1 S= 32.07 4 O= 64.00 Molar mass= 151.5304
How many atoms are present in 1.5 mol of sulfuric acid?
A mol = 6,022x10^23 atoms 1,5 mol = 9,033x10^23 atoms Always.
How many atoms are in 1.45 g of Ag?
Convert 1 gram Fe to moles by dividing by molecular weight, in this case: 55.8 g/mol.So 1 gram = 1/55.8 or 0.0179 moles of Fe. 1 mole of any substance contains Avogadro's number of atoms or 6.022e23. So multiply 0.0179 by 6.022e23 to get:1.079*1022 atoms of Fe (iron)
Arrange the following from the smallest number of representative particles to the largest number of representative particles1.25x1025 atoms of Zn 3.56 mol Fe 6.78x1022 molecules of glucose?
