How many moles of iron atoms are contained in 4.09g of iron
Divide it by Avogadro constant.There are 0.0088 moles
What is the mass of sliver in 3.4g AgNo3
There is no direct relationship between atoms of boronand grams of boron. Use Avogadro's number to convert atoms to moles, and the atomic mass to convert moles to grams.Since you are converting from atoms B, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of grams of B, so this goes in the numerator (on the top) of the last factor.atoms B1.00 mole B10.8 gram = g B6.02E+23 atom B1.00 mole BNote that the units atoms boron "cancel out" in the first factor and you are left in units of moles. Moles cancel outin the second factor and the final units are grams boron.
To calculate the number of moles in a substance, divide the number of atoms or molecules by Avogadro's number (6.022 E23). Alternately, divide the mass of the substance by its molar mass.
Each mole of boron atoms has a mass of 10.811 grams, as indicated by the gram atomic mass or weight of boron. Therefore, 585 moles has a mass of about 6.32 X 103 grams, to the same number of significant digits as 585.
You divide the number of atoms by avagadro's number. Avagadro's number is 6.022x10^23 atoms/molecules / mole. The best way to remember this is by the units, atoms in each mole.
0.54 moles of atoms are in 7.00 grams of Carbon 13. The formula used to calculate the number of moles of atoms is No. of moles = Mass divided by Relative tomic Mass or 7 divided by 13.
1 mole of an element is equal to avogadro's constant which is 6.022*10 raised to 23.therefore with the number of moles you have,you can use the constant to get your answer
The number of hydrogen atoms in 0,050 moles of C3H8O3 is 2,39.10e23.
The number of atoms in 1,2 moles of pure aluminum is 7,2265690284.1023.
The total number of atoms in 3.5 moles of calcium is 21,0774929995.10e23.
Number of atoms: 3,72.10e+20Number of moles: 6,18.10e-4
To convert grams to moles you use the molar mass of iron (55.8 grams per mole). Divide the numbers to get the number of moles: 500 g Fe / 55.8 g/mol = 8.96 mol Fe. To calculate the number of atoms, use Avogadro's Number (6.02*1023). Multiply the number of moles and Avogadro's number: 8.96 mol * (6.02*1023) = 5.39*1024 Fe atoms.
1o g aluminium is equal to 0,37 moles or 2,22819211709.10e23 atoms.
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
Calculate the number of moles in 0.135 grams of HNO3?
Depends on the volume, pressure, and temperature, the balloon can occupy different volume of helium. You can calculate the number of helium atoms in the balloon using the ideal gas law :: PV=nRT (Pressure)(volume) = (# of moles)(constant)(temperature) Once you have Pressure, volume and temperature, you can solve for n, which is the number of moles. And then you can multiply the number of moles by the Avocadro's number and get the number of atoms.
To convert the number of atoms to moles: You need the number of atoms in a substance which is usually given. Ex. 1.65 × 1024 atoms of Magnesium. Then the formula is as follows: # of atoms ÷ (Avogrado's Constant) = # moles 1.65 × 1024 atoms ÷ (6.02 × 1023) = 2.74 moles of Mg
Molar mass is irrelevant. Number of moles is equal to number of atoms divided by Avagadro's number
The number of atoms is 18,066.10e23.
1 mole of helium has 6.023 x 1023 atoms. So, 1.5 mole of helium will have 9.035 x 1023 atoms.
The number of iron moles is x(atoms)/6,022140857.10e23.
Approx. 4 moles.
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
