40*4=160g
To find the mass of argon in grams for 100 moles, you can use the molar mass of argon, which is approximately 40 grams per mole. Therefore, the mass of 100 moles of argon would be calculated as follows: 100 moles × 40 g/mole = 4000 grams. Thus, there are 4000 grams of argon in 100 moles.
2.3 × 1024 atoms of Ar
1,67.1024 argon atoms is equal to 2,773 moles.
A mole of argon includes Avogadro's Number of atoms of argon. Therefore, the answer is (3.0 X 1024)/(6.022 X 1023) or 5.0 moles, to the justified number of significant digits.
To find the number of argon atoms in a 40.0-g sample, you first need to calculate the number of moles of argon in the sample using the molar mass of argon (39.95 g/mol). Then, you can use Avogadro's number (6.022x10^23 atoms/mol) to determine the number of atoms in that many moles of argon.
One mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, one million argon atoms would be equivalent to roughly 1.66 x 10^-17 moles of argon atoms.
0.125 moles of argon gas contain 7.52 x 10^23 atoms.
To find the number of argon atoms, we first need to convert the amount from millimoles to moles by dividing by 1000. Next, we use Avogadro's number, which is 6.022 x 10^23 atoms/mol, to calculate the number of atoms in 7.66 x 10^2 moles of argon. The result is approximately 4.61 x 10^26 argon atoms.
To find the number of argon atoms in 1.5x10^2g of argon, we first need to determine the molar mass of argon. The molar mass of argon is approximately 39.95 g/mol. Next, we convert the given mass to moles by dividing by the molar mass. Finally, we use Avogadro's number (6.022x10^23) to convert moles to atoms. The number of argon atoms in 1.5x10^2g of argon would be approximately (1.5x10^2g / 39.95g/mol) x 6.022x10^23 atoms.
1,012 mole of bromine for the diatomic molecule.
40*4=160g
To find the number of moles in 160g of bromine molecules, we first need to determine the molar mass of bromine which is approximately 79.9 g/mol. Then, we can use the formula: moles = mass / molar mass. Therefore, moles = 160g / 79.9 g/mol ≈ 2 moles.
To calculate the number of atoms in 35.4g of argon, you need to divide the given mass by the molar mass of argon to get the number of moles, and then multiply by Avogadro's number (6.022 x 10^23 atoms/mol). The molar mass of argon is approximately 39.95 g/mol. So, 35.4g / 39.95 g/mol = 0.887 moles of argon. Multiplying by Avogadro's number gives 0.887 mol x 6.022 x 10^23 atoms/mol ≈ 5.34 x 10^23 atoms.
To find the number of moles of argon in 37.9 g, you need to use the molar mass of argon, which is 39.95 g/mol. Divide the given mass by the molar mass to get the number of moles. So, 37.9 g / 39.95 g/mol = 0.95 moles of argon.
