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.
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.
To find the number of moles, you need to divide the given mass (in grams) by the molar mass of CCl4, which is 153.82 g/mol. Therefore, 56 g / 153.82 g/mol = 0.364 moles of CCl4.
Divide the Molar Mass of C and Cl4 by 56 to get your awnswer!
To prepare a 2 M solution of KOH, you would need to calculate the moles of KOH required first. Then use the formula mass of KOH (56 g/mol) to convert moles to grams. First, calculate the moles needed: 2 moles/L * 0.25 L = 0.5 moles. Then, convert moles to grams: 0.5 moles * 56 g/mole = 28 grams of KOH needed.
To calculate the number of grams of iron, you need to convert the number of iron atoms (6.02 x 10^23) into moles by dividing by Avogadro's number (6.022 x 10^23 atoms/mol). Then, multiply the number of moles of iron by the molar mass of iron (55.85 g/mol) to find the grams of iron. This would result in approximately 55.85 grams of iron.
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
moles = weight in grams / molecular weight = 56 / 28 = 2 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.

Then, multiply the number of moles of iron by the molar mass of iron (55.85 g/mol) to find the grams of iron. This would result in approximately 55.85 grams of iron.
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
To calculate the number of iron atoms in the 30g serving of cornflakes, first determine the number of moles of iron in the serving using the molar mass of iron (55.85 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of iron atoms in the serving.

Milli means one thousandth. So there are 1000 millimoles in a mole. Therefore 56/1000 gives you 0.056 moles.
