How many moles of helium are in a balloon filled with 6.02 1025 atoms of helium?
To find the number of moles of helium, you can use Avogadro's number, which is approximately (6.02 \times 10^{23}) atoms per mole. Divide the total number of helium atoms ( (6.02 \times 10^{25}) atoms) by Avogadro's number: [ \text{Moles of helium} = \frac{6.02 \times 10^{25} \text{ atoms}}{6.02 \times 10^{23} \text{ atoms/mole}} \approx 100 \text{ moles}. ] Thus, there are about 100 moles of helium in the balloon.
What do you think makes balloon stay up?
balloon stay up because of the air inside it. to make the balloon stay up the air should be light. inside the balloons you can find the air we called helium. helium is a light air that makes the balloon stay up. that's why if you blow the balloon it wont float because the air that comes from your mouth is not helium but carbon dioxide and carbon dioxide is heavier compared to helium so it wont float.
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
How many helium atoms are in 542 kg of helium?
To find the number of helium atoms in 542 kg of helium, you need to first calculate the number of moles of helium in 542 kg using the molar mass of helium, which is 4 grams/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of helium to atoms.
How many helium atoms are there in a helium blimp containing 590 kg of helium?
To find the number of helium atoms, we need to convert the mass of helium to moles and then use Avogadro's number to convert moles to atoms. The molar mass of helium is 4 g/mol. First, convert 590 kg to grams (590,000 g). Then, divide by the molar mass of helium to find moles, and finally multiply by Avogadro's number (6.022 x 10^23 atoms/mol) to get the number of atoms.
How many helium atoms are there in a helium blimp containing 431 kg of helium?
To find the number of helium atoms in a helium blimp, you would first need to convert the mass of helium (431 kg) to moles using the molar mass of helium. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of helium atoms.
How many grams of helium does a 25.0 L balloon contain at 102.0 kPa and 24 degrees C?
To find the mass of helium in the balloon, you need to use the ideal gas law equation: PV = nRT. First, find the number of moles of helium using PV = nRT, and then convert moles to grams using the molar mass of helium (4.00 g/mol). Finally, you can calculate the mass of helium in the balloon.

How many helium atoms are there in a helium blimp containing 533 kg of helium?
To find the number of helium atoms in the blimp, you first calculate the number of moles of helium in 533 kg of helium using the molar mass of helium. Then, you use Avogadro's number (6.022 x 10^23) to convert moles to atoms. The final answer will give you the number of helium atoms in the blimp.
What is the mass in grams of 3.40x10 22 atoms He?
To find the mass of 3.40x10^22 helium atoms, you need to know the molar mass of helium, which is 4.0026 g/mol. So, the mass of 3.40x10^22 helium atoms would be 3.40x10^22 atoms * (4.0026 g/mol/6.022x10^23 atoms/mol) ≈ 2.27 grams.
What is the Total mass of3.01 x 10 23 atoms of helium gas?
To find the total mass of 3.01 x 10^23 atoms of helium gas, you need to multiply the number of atoms by the atomic mass of helium. Helium's atomic mass is approximately 4 atomic mass units. So, the total mass would be 3.01 x 10^23 atoms * 4 amu.
Why Balloon filled with helium does not raise indefinitely?
If you blow up a balloon then the helium inside it will run out after about 2 days. After those two days (maybe 3) there will be no helium left, but you will find that the balloon is still up and rounded but not as big as before. This is because the helium had got warm inside the balloon and transfered into a liguid, then that got evaporated and turned to a gas. Therefore the gas isn't helium. Because as it changed to a liquid, the liquid picked up other parts of gas and that transfered to a liquid with it to. So it is just an ordinary gas, Oxygen. Thank You. Lucie
