How many moles does 205 g of helium contain?
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.
How many moles are present in 205 g 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.
How many moles are present in 40g of helium?
4 g of helium is equivalent to 1 mole of helium
How many moles of helium are in sixteen gallons of the element?
The answer is 2,7 moles.
Convert 1.2 x 1024 atoms of helium to moles?
How many moles are there in 9.0333x1024 atoms of helium

How many moles of Helium are present in 5.66 moles of H2O?
H2O or water doesn't have any helium in it.
How many moles of helium gas (he) are present in 7.2 liters of helium gas at standard conditions?
The number of moles of helium is 0,32.
How many moles are present in 205 g 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.
How many moles are present in 0.12g 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.
How many moles are present in 40g of helium?
4 g of helium is equivalent to 1 mole of helium
How many grams are in 0.775 moles of helium?
The mass of helium equivalent to 0,775 moles is 3,102 g.
How many moles of helium are in sixteen gallons of the element?
The answer is 2,7 moles.
How many moles of Helium are in 6.46 g of Helium?
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
Convert 1.2 x 1024 atoms of helium to moles?
How many moles are there in 9.0333x1024 atoms of helium
How many grams are in 5.82 moles of helium?
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
How many moles of he are in 16 of the element?
There are approximately 4.0 moles of Helium in 16 grams of the element.
