The formula unit of gold is generally considered to be a single atom. Therefore, the answer is 5.6 X Avogadro's Number or about 3.4 X 1024.
The answer is 0,364 moles.
To find the number of atoms we need to find number of moles of Fe in 312.0 grams. Molar weight of Fe = 56 Number of moles of Fe in 312 grams = 312/56 =5.571 moles. 1 mole of Fe has Avogadro number of atoms. So 5.571 moles of Fe has atoms = 5.571 * Avogadro number. Avogadro number = 6.022 * 10^23 So total atoms = 5.571 * 6.022 * 10^23 = 33.548 * 10^23 * means multiply, ^ means raised to power.
There are more atoms of sulfur in 16 grams than there are atoms of iron in 56 grams.
The Answer is.56 moles OR 0.56 moles
Divide the Molar Mass of C and Cl4 by 56 to get your awnswer!
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
The answer is 0,364 moles.
moles = weight in grams / molecular weight = 56 / 28 = 2 moles

mass/mr = number of moles0.0024g / 30 / 56 = 1/700000 moles of Fe x (6x10^23) =8.571428571x10^17 atoms of Fe
The number of atoms is 28,099.10e23.
The molecular mass of selenium is 78.96g/mol. You need to convert micrograms to grams. i.e. 56/1,000,000 is 0.000056 grams. 0.000056/78.96 is 0.00000071 moles.
Depending upon how precise your masses are, KOH has a molar mass of about 56, so your answer is about 34/56.
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
