4 g of Helium will have 1 mole.
So, 6.45 x 1010 g of Helium will have 1.61 x 1010 mole.
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.
To find the number of moles present in 205 g of helium, we need to use the molar mass of helium, which is approximately 4 g/mol. Divide the given mass by the molar mass to get the number of moles. In this case, 205 g / 4 g/mol = 51.25 moles of helium.
16 grams of oxygen how many moles is 0,5 moles.
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
The answer is 2,7 moles.
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
The mass of helium equivalent to 0,775 moles is 3,102 g.
He = helium 16 grams He (1 mole He/4.003 grams) = 3.99 moles He You can call it 4.0 moles He
There are approximately 4.0 moles of Helium in 16 grams of the element.
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.
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
To find the number of moles present in 205 g of helium, we need to use the molar mass of helium, which is approximately 4 g/mol. Divide the given mass by the molar mass to get the number of moles. In this case, 205 g / 4 g/mol = 51.25 moles of helium.
16 grams of oxygen how many moles is 0,5 moles.
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
The number of moles of helium is 0,32.
H2O or water doesn't have any helium in it.
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.
