1 mole He is 4.0 g. Use as a conversion factor to change 0.12 g He to moles.
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
There are 4.17 moles of H2O present in 75.0g of H2O.
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.
There are 6 moles of sulfur present in 3 moles of aluminum sulfate, because aluminum sulfate has a 2:3 ratio of aluminum to sulfur.
There are 5 moles of sulfur in 5 moles of H2SO4, as there is 1 mole of sulfur in each mole of H2SO4.
H2O or water doesn't have any helium in it.
The number of moles of helium is 0,32.
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.
To calculate the number of moles, you need to divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 g/mol. Therefore, the number of moles in 205g of helium would be 205g / 4g/mol = 51.25 mol.
4 g of helium is equivalent to 1 mole of helium
The mass of helium equivalent to 0,775 moles is 3,102 g.
The answer is 2,7 moles.
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
How many moles are there in 9.0333x1024 atoms of helium
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
There are approximately 4.0 moles of Helium in 16 grams of the element.
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
