2 moles equals 8 g of helium or 12.046 x 1023 atoms
1 mole of helium equal 4,002602(2) 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.
How many moles are there in 9.0333x1024 atoms of helium
To calculate the amount of helium in the balloon, we need to convert the mass of helium gas to moles using the molar mass of helium. The molar mass of helium is 4 g/mol. So, 0.54 grams of helium is equal to 0.54/4 = 0.135 moles of helium. Finally, we can use Avogadro's principle to convert moles to the number of helium atoms present in the balloon.
2 moles of helium contain more atoms than 1 mole of gold. Since 1 mole of any substance contains Avogadro's number of atoms (approximately (6.022 \times 10^{23})), 2 moles of helium would have about (1.204 \times 10^{24}) atoms, while 1 mole of gold has approximately (6.022 \times 10^{23}) atoms. Therefore, 2 moles of helium have double the number of atoms compared to 1 mole of gold.

No it is true. 1 mole of helium is 4 g. So 2 moles will be 8 g.

To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
The number of moles of helium is 0,32.
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
The mass of 1,5 moles of helium is 6,003 903 g.
H2O or water doesn't have any helium in it.
The mass of helium equivalent to 0,775 moles is 3,102 g.
To calculate the amount of helium in the balloon, we need to convert the mass of helium gas to moles using the molar mass of helium. The molar mass of helium is 4 g/mol. So, 0.54 grams of helium is equal to 0.54/4 = 0.135 moles of helium. Finally, we can use Avogadro's principle to convert moles to the number of helium atoms present in the balloon.
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.
