lets estimate ... helium weighs 4 g / 22.4 L at stp. Air is about (.8*28 +.2*32) or 28.8 g / 22.4 L at stp. this gives a lifting ability of 28.8-4 = 24.8 g for 4 g of helium.
210 / 24.8 = 8.468 times as much. or 8.468 x 4 = 33.872 g He
or 8.468 x 22.4 = 189.6832 Liters of He at stp.
This ignores any weight of a balloon to hold the helium or a 'basket' to hold the 210 g object. This is about 6.5 or 7 cubic feet of He, a large amount. weight of the balloon will become important.
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
The molar mass of helium is 4 g/mol. This means that 1 mole of helium has a mass of 4 grams. Since 2.5 moles of helium have a mass of 10 grams, the atomic mass of helium is 4 grams/mol.
To find the number of moles in 6.071 grams of helium, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 grams per mole. Therefore, 6.071 grams / 4 grams/mol ≈ 1.52 moles of helium.
2 moles of helium is equal to approximately 8 grams, since the atomic mass of helium is 4 grams per mole.
Helium-filled objects "float" in most substances that aren't primarily hydrogen or helium because of it's less dense. Helium has a weight of 0.1785 grams per liter. Nitrogen, on the other hand, which makes up 80% of the air we breathe, weighs 1.2506 grams per liter. Things that are lighter over the same surface area are more buoyant.However, helium isn't the lightest element. Hydrogen, weighing a mere 0.08988 grams per liter, is. The reason hydrogen isn't used as commonly as helium to fill things is because of the high flammability of hydrogen, with a small spark causing a hypothetical hydrogen balloon to explode.
You can measure bacteria in nano grams as only 1,000,000,000 nano grams are in 1 gram ,so that you might not even be able to see the object what you weighing in nano gram.
If the object is small, weighing no more than a pound or two. A kilogram ( 1,000 grams ) = 2.2 pounds, approx. Thus, anything larger should be measured in Kg, since it is much simpler to describe an object's weight as 3.5 kg, rather than 3,500 grams.
The mass of an object (or its weight) has nothing to do with its ability to float ...consider feathers, rocks, people, and battleships.The determining quantity is the object's density, which is the ratio of its massto its volume.
It depends on what you are weighing.
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
The molar mass of helium is 4 g/mol. This means that 1 mole of helium has a mass of 4 grams. Since 2.5 moles of helium have a mass of 10 grams, the atomic mass of helium is 4 grams/mol.
an ounce is 28.3 grams. it does not matter what you are weighing.

To find the number of moles in 6.071 grams of helium, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 grams per mole. Therefore, 6.071 grams / 4 grams/mol ≈ 1.52 moles of helium.
A top loading balance is used to accurately measure the mass of solid objects. It is typically used in laboratories for tasks such as weighing chemicals, food samples, or other materials where precision and accuracy are required.
