How many helium atoms are there in a helium blimp containing 535 kg 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…..
How many atoms are there is a helium blimp containing 526 kg of helium?
8.06×1028 He atoms.
How many helium atoms are there in a helium blimp containing 540 kg of helium?
There are 8.13 × 1028 He atoms in 540 kg He.
How many atoms are in a helium?
Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Since 2 + 2 = 4, we know that the mass number of the helium atom is 4….Mass Number.

How many helium atoms are in a helium blimp?
Therefore, 7. 43×1028 helium atoms are present in 494kg of helium.
How many helium atoms are there in a helium blimp containing 542 KGKG of helium?
Answer and Explanation: Thus, there are 8.14×1028 8.14 × 10 28 atoms of helium in 541 kg of helium.
How many numbers of atoms are there in 22.4 l of he helium?
Explanation: A volume of 22.4⋅L gas under standard conditions of temperature and pressure (1⋅atm,273.15⋅K) specifies a MOLAR quantity of gas. That is there are 6.022×1023 individual helium atoms.
How many helium atoms are there in a helium blimp containing 5.36 kg of helium?
The Number of Atoms: It is equal to 6.023×1023 6.023 × 10 23 .
How big is a helium atom?
Fig3_1 The helium atom The nucleus and each of its four particles are spherically symmetric. The size of the helium nucleus is about 1 fermi, or 1 fm, which is equivalent to 10-15 m. The atom is about 100,000 times bigger than the nucleus, with an atom size of about 105 fm or 10-10 m.
What is the size of a helium atom?
140 pm
Helium/Van der Waals radius
How many helium atoms are in a liter?
A volume of 22.4⋅L gas under standard conditions of temperature and pressure (1⋅atm,273.15⋅K) specifies a MOLAR quantity of gas. That is there are 6.022×1023 individual helium atoms.
