How Many Atoms of Helium are in a Balloon?
Calculating the Number of Helium Atoms
Moles of He: 0.47
Number of Atoms: 0.47 x 6.02 x 10²³ = 2.83 x 10²³ atoms
Final Answer: 2.83 x 10²³ atoms
Explanation: To find the number of atoms of helium in a balloon containing 0.47 moles of the gas, you can use Avogadro's number. Avogadro's number is defined as 6.022 x 10^23 atoms per mole. By multiplying the number of moles by Avogadro's number, you can determine the number of atoms.
Number of atoms = number of moles x Avogadro's number
Number of atoms = 0.47 moles x (6.022 x 10^23 atoms/mole)
Number of atoms = 2.82334 x 10^23 atoms
How do you calculate the number of atoms of helium in a balloon with 0.47 moles of gas?
To calculate the number of atoms of helium in a balloon with 0.47 moles of gas, you can use Avogadro's number. Simply multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the total number of atoms present in the balloon, which in this case is 2.83 x 10²³ atoms.
