4 g of Helium = 1 mole
So, 205 g of Helium = 51.25 moles
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.
Helium exists as a monatomic noble gas. Its atomic mass is 4.0 as can be obtained from the periodic table. The amount of helium in a 205g pure sample is given by 205/4.0 which equates to roughly 51 moles.
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
4 g of helium is equivalent to 1 mole of helium
How many moles are there in 9.0333x1024 atoms of helium
The answer is 2,7 moles.

H2O or water doesn't have any helium in it.
The number of moles of helium is 0,32.
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
1 mole He is 4.0 g. Use as a conversion factor to change 0.12 g He to moles.
4 g of helium is equivalent to 1 mole of helium
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
The mass of helium equivalent to 0,775 moles is 3,102 g.
How many moles are there in 9.0333x1024 atoms of helium
The answer is 2,7 moles.
0.46 divided by the formula weight of helium (4) 0.46/4=0.115 or 0.12 moles of Helium
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
