How many atoms are in a helium 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.)
How many kg is a helium atom?
1 Answer. Well let's see, we got the mass of a SINGLE helium atom…. 6.65×10−27⋅kg …
How many atoms are there in helium?
1 He molecule contains only 1 atom(as helium is monoatomic).
How many atoms are in the balloon if there are 2 moles of helium he in it?
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 1.20 x 1024 atoms.

How many atoms are in the balloon if there are 2 moles of helium He in it?
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 1.20 x 1024 atoms.
How do you calculate number of atoms?
# of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole. In the above formula density times volume is just the mass.

How do you calculate atoms?
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
How many atoms are in a gram?
6.022 × 1023 The definition of Avogadro's number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight.
How do I calculate moles?
The unit is denoted by mol.
- The formula for the number of moles formula is expressed as.
- Given.
- Number of moles formula is.
- Number of moles = Mass of substance / Mass of one mole.
- Number of moles = 95 / 86.94.
What is the mass of 1 helium atom?
4.002602 The atomic weight of helium is 4.002602, the average that reflects the typical ratio of natural abundances of its isotopes. Atomic weight is measured in atomic mass units (amu), also called daltons.
How do you find the number of atoms in a gas?
I then used the formula n=m/M to find the amount of substance. Then, to find the number of atoms, I used the formula n=N/NA.
How do you calculate an atom’s mass?
In an element atomic mass of an atom can be calculated by adding the mass of protons and neutrons.

How do you calculate number of atoms in a compound?
- Use the periodic table to determine the molar mass of the element.
- Divide the given mass in grams by the molar mass to find the number of moles.
- Multiply the number of moles by Avogadro's number to obtain the number of atoms.
How do you convert moles to atoms on a calculator?
Converting moles to atoms is as simple as multiplying the number of moles by the 6.022 * 10^23 because by definition that is what a mole represents.
How do u calculate atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How do you find the number of atoms?
- Use the periodic table to determine the molar mass of the element.
- Divide the given mass in grams by the molar mass to find the number of moles.
- Multiply the number of moles by Avogadro's number to obtain the number of atoms.
How do you convert kg to atoms?
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
How do you find the atom?
They are:
- Mass → Moles and Moles → Atoms.
- 196.967 u . …
- So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply the given mass by the reciprocal of the molar mass. …
- Once you have moles, multiply by Avogadro's number to calculate the number of atoms.
