How many helium atoms are in the balloon?
To say a balloon has a mole of helium atoms in it means it contains 6.02 * 10^23 atoms of helium. If a balloon has 3.6 * 10^25 atoms, it means it has more than a mole of atoms (since 25 zeros means its a larger number than 23 zeros.)Click to see full answer. Also…
To say a balloon has a mole of helium atoms in it means it contains 6.02 * 10^23 atoms of helium. If a balloon has 3.6 * 10^25 atoms, it means it has more than a mole of atoms (since 25 zeros means its a larger number than 23 zeros.)Click to see full answer. Also know, how many atoms are in 1g of helium?1 mole of He contains 6.023×10^23 atoms. 1 mole of He = 4 gm of He. So, 20 gm of He contains — (20÷4)×6.023×10^23 atoms = 3.011×10^24 He atoms.Additionally, how many helium atoms are in a helium blimp? The molar mass of helium = 4.00 g/mol. This means that 1 mole of helium atoms weighs 4 gram. In this case you have 494 kg which is 494.000 grams. Also Know, how many atoms are in 2 moles of helium? Find helium on the periodic table in the top right corner. If I fill up a balloon with 2 moles of helium atoms, how many helium atoms would be in the balloon? If 1 mole of atoms is 6.02 x 1023 atoms, then 2 moles of atoms would be equal to 1.2 x 1024 atoms.How many helium atoms are there in a helium blimp containing 535 kg of helium?Moles of helium=535⋅kg×103⋅g⋅kg−14.0⋅g⋅mol−1=133750⋅mol. And then (ii) we mulitply this molar quantity by Avogadro’s number. NA=6.022×1023⋅mol−1 to get the number of helium atoms..
