By the definition of Avogadro's Number, each mole contains 6.022 X 1023 molecules. Therefore, (9.25 X 1024)/(6.022 X 1023) or 15.4 moles are required, to the justified number of significant digits.

A flask contains 0.310 of liquid bromine Determine the number of bromine molecules present in the flask?
.310 MOLES 6.022*(10^23 ) molecules --------------- times ------------------------------------ = 1.8668 * 10^23 molecules 1 mole because there are 3 sig figs the answer should reflect that number. so the answer is 1.87 * 10^23 molecules
How many moles of ammonium ions are in 4.50 mol NH4 2CO3?
There are 9 moles of NH4 (Ammonium ions) in Ammonium carbonate. There are 2 moles of NH4 per molecule and 4.5 molecules, so 2 moles times 4.5 is 9 moles.
Calculate the number of atoms in 0.543 mol of silicon?
The number of molecules in a mole is known as "Avogadro's Number" and is about 6.002 times ten to the twenty-third power. Therefore, the number of moles is 0.543 X 6.022 = 3.27 times ten to the twenty-third power. (This answer will be the same for moles of any substance.) Silicon is generally regarded as having only one atom per molecule, so that the number of atoms will be the same as the number of moles. Under certain conditions, however, silicon may occur as polyatomic molecules, and in such an instance the answer would be different.
In how many moles are 8.37 times 10 power 23 molecules of N2?
2 (atoms N / molecule N2) * 8.5*10+24 (molecules N2) / 6.02*10+23 (atoms N / mole N-atoms) = 28 mole N-atoms
How many atoms are present in 8.00 moles of chlorine?
If the chlorine is in its normal state of diatomic molecules, there are 16.0 moles of chlorine atoms in 8.00 moles of chlorine. The number of atoms is then 16 times Avogadro's number = 9.64 X 1024, to the justified number of significant digits.
How many moles are in 3.4 times 10 to the 23 power molecules of H2SO4?
.565 MOLES
Convert 5.3 times 10 raised to the 25 power molecules of CO2 to moles?
The answer is 88 moles.
Number of moles of hydrogen atoms in 10.7 mol water?
H2O is water. One mole of water contains 2 moles of hydrogen atoms. Therefore, 10.7 moles of water contain 21.4 moles of hydrogen atom.
How many moles of CaCl2 contains 1.26 times 10 24 formula units CaCI2?
The answer is 2,09 moles.
A mass of ammonia weighs 2.00g.What mass of sulphur dioxide contains the same number of molecules as are in 2.00g ammonia?
To find the mass of sulfur dioxide (SO₂) that contains the same number of molecules as 2 grams of ammonia (NH₃), you can use the concept of moles and the molar mass. **Find the number of moles of ammonia:** [ \text{Moles of NH₃} = \frac{\text{Mass of NH₃}}{\text{Molar mass of NH₃}} ] The molar mass of ammonia (NH₃) is approximately 17 grams/mol. **Use Avogadro's Number:** According to Avogadro's number, 1 mole of any substance contains the same number of entities (atoms, molecules, etc.), which is approximately (6.022 \times 10^{23}). **Find the number of molecules of ammonia:** [ \text{Number of NH₃ molecules} = \text{Moles of NH₃} \times (6.022 \times 10^{23}) ] **Convert to moles of sulfur dioxide:** Since the number of molecules is the same for both substances, the moles of sulfur dioxide (SO₂) would be the same as the moles of ammonia. [ \text{Moles of SO₂} = \text{Moles of NH₃} ] **Find the mass of sulfur dioxide:** [ \text{Mass of SO₂} = \text{Moles of SO₂} \times \text{Molar mass of SO₂} ] The molar mass of sulfur dioxide (SO₂) is approximately 64 grams/mol. Now, you can substitute the values into the equations to find the mass of sulfur dioxide.

How many moles is 2.80 times 10 to the twenty third power atoms of silicon?
The answer is 0,465 moles.
How many molecules are in 24 moles of N2O?
24 times Avogadro's number (6.022 x 10 to the 23).
How many moles of ammonium ions are in 4.50 mol NH4 2CO3?
There are 9 moles of NH4 (Ammonium ions) in Ammonium carbonate. There are 2 moles of NH4 per molecule and 4.5 molecules, so 2 moles times 4.5 is 9 moles.

How many moles of water does 6.02 times ten to the twenty third power?
6.02 x 1023 is Avogadro's number, to 3 significant digits. A mole of anything is that number of particles (in the case of water, molecules).
In how many moles are 8.37 times 10 power 23 molecules of N2?
2 (atoms N / molecule N2) * 8.5*10+24 (molecules N2) / 6.02*10+23 (atoms N / mole N-atoms) = 28 mole N-atoms
