The answer is 2,7 moles.
To convert atoms to moles, you divide by Avogadro's number, which is 6.022 x 10^23. 1.2 x 10^24 atoms of helium is equivalent to 2 moles of helium.
To convert grams to moles, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 26.7kg of helium is equal to 26,700g, which would be 6,675 moles of helium.
To calculate the number of moles of helium in 0.255g, you need to divide the mass by the molar mass of helium (4g/mol). This would be 0.255g / 4g/mol = 0.06375 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.
The number of moles of helium is 0,32.
H2O or water doesn't have any helium in it.
The mass of helium equivalent to 0,775 moles is 3,102 g.
The answer is 2,7 moles.
To find the number of moles of Helium in 6.46 g, you need to divide the given mass by the molar mass of Helium (4 g/mol). 6.46 g / 4 g/mol = 1.615 moles of Helium.
To convert atoms to moles, you divide by Avogadro's number, which is 6.022 x 10^23. 1.2 x 10^24 atoms of helium is equivalent to 2 moles of helium.
To calculate the number of moles in 0.12g of helium, you need to use the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 0.12g of helium is equivalent to 0.12g / 4g/mol = 0.03 moles of helium.
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
To convert grams to moles, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 26.7kg of helium is equal to 26,700g, which would be 6,675 moles of helium.
To calculate the number of moles of helium in 0.255g, you need to divide the mass by the molar mass of helium (4g/mol). This would be 0.255g / 4g/mol = 0.06375 moles of helium.
There are approximately 4.0 moles of Helium in 16 grams of the element.
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.
