No of moles of atoms={total mass of substance(or)total mass of molecules }x#
gram molecular weight of one molecule
Where # =atomicity of molecule i.e no.of atoms in a molecule
ex: atomicity of co2=3 since there are three atoms in a co2 (c,o,o) molecule.

How many atoms of chlorine are there in 445g of lead 2 chloride?
To determine the number of atoms of chlorine in 445g of lead chloride (PbCl2), you need to calculate the number of moles of PbCl2 in 445g and then multiply it by the number of chlorine atoms in one PbCl2 molecule. First, calculate the number of moles of PbCl2 using the formula: moles = mass / molar mass. The molar mass of PbCl2 is 278.1 g/mol, so moles = 445g / 278.1 g/mol = 1.6 moles. Since there are two chlorine atoms in one molecule of PbCl2, the total number of chlorine atoms is 2 * 1.6 moles = 3.2 moles of chlorine atoms. To convert moles to atoms, multiply by Avogadro's number. Therefore, there are 3.2 moles * 6.022 x 10^23 atoms/mole = 1.9264 x 10^24 atoms of chlorine in 445g of PbCl2.
How do you calculate moles from molarity?
Number of Moles = concentration * volume (in litres)
How many H atoms are there in 4.37 moles of H?
The number of atoms is 52,63.10e23.
How do you convert atoms to grams with Avogadro's number?
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
How can you calculate no of moles from no of atoms?
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.

First, calculate the number of moles of PbCl2 using the formula: moles = mass / molar mass. The molar mass of PbCl2 is 278.1 g/mol, so moles = 445g / 278.1 g/mol = 1.6 moles. Since there are two chlorine atoms in one molecule of PbCl2, the total number of chlorine atoms is 2 * 1.6 moles = 3.2 moles of chlorine atoms. To convert moles to atoms, multiply by Avogadro's number. Therefore, there are 3.2 moles * 6.022 x 10^23 atoms/mole = 1.9264 x 10^24 atoms of chlorine in 445g of PbCl2.
What is the number of atoms in 1.2 moles of pure aluminum?

What is the total number of atoms in 3.5 moles of calcium?
The total number of atoms in 3.5 moles of calcium is 21,0774929995.10e23.
How many moles in NaCHO3?
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.
What is the number of atoms in 1.5 moles of helium if you calculate it?
1 mole of helium has 6.023 x 1023 atoms. So, 1.5 mole of helium will have 9.035 x 1023 atoms.
What is the number of atoms of tin in 3 moles of tin?
The number of atoms is 18,066.10e23.
How to convert grams to atoms?
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.
How do you calculate moles from molarity?
Number of Moles = concentration * volume (in litres)
How many atoms of chlorine are in 2.00 moles of CCl4?
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
molality How many sulfur atoms are in 1.56g sulfur When atomic mass of sulfur is 32.06g/mol?
To find the number of sulfur atoms in a given mass of sulfur, you can use the following steps: Determine the number of moles of sulfur using the formula: moles = mass molar mass moles= molar mass mass Given that the molar mass of sulfur ( S S) is 32.06 g/mol and the mass ( m m) is 1.56 g: moles = 1.56 g 32.06 g/mol moles= 32.06g/mol 1.56g Once you have the moles of sulfur, you can use Avogadro's number (6.022 x 1 0 23 10 23 mol − 1 −1 ) to find the number of atoms: number of atoms = moles × Avogadro’s number number of atoms=moles×Avogadro’s number Let's calculate it: moles = 1.56 g 32.06 g/mol ≈ 0.0488 mol moles= 32.06g/mol 1.56g ≈0.0488mol number of atoms = 0.0488 mol × ( 6.022 × 1 0 23 mol − 1 ) number of atoms=0.0488mol×(6.022×10 23 mol −1 ) number of atoms ≈ 0.0488 × 6.022 × 1 0 23 number of atoms≈0.0488×6.022×10 23 number of atoms ≈ 3.0 × 1 0 22 number of atoms≈3.0×10 22 Therefore, there are approximately 3.0 × 1 0 22 3.0×10 22 sulfur atoms in 1.56 g of sulfur.
