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.

What has more atoms 2.88 grams of helium atoms or 16.4 grams of zinc atoms?
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
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.
How many moles in 6.071grams of helium?
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.
What does 2 moles of helium equal?
2 moles of helium is equal to approximately 8 grams, since the atomic mass of helium is 4 grams per mole.
What makes helium float?
Helium is lighter than the surrounding air, which makes it less dense and causes it to float. This buoyant force is due to the difference in density between helium and the air, allowing helium balloons and airships to rise in the atmosphere.
What is measured in nanograms?
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.
Can an object weighing at ten grams float in water?
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.
Should grams be used to measure the weight of an object?
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.
Is 3610 grams heavy?
It depends on what you are weighing.
How many grams are in 5.82 moles of helium?
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
What has more atoms 2.88 grams of helium atoms or 16.4 grams of zinc atoms?
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
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.
How many grams of myrrh powder in an ounce?
an ounce is 28.3 grams. it does not matter what you are weighing.
What is the instrument used for measuring grams?
Weighing scales
What metric unit is best for weighing crackers?
grams
How many moles in 6.071grams of helium?
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.
What is the use of top loading balance?
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.
