How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
How many moles are present in 205g 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.
How many moles are contained in 1.23 grams of krypton?
# moles = mass / molar mass = 1.23g / 83.80g/mol =1.47x10^-2 moles There are 1.47x10^-2 moles in 1.23g of krypton
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
How many moles of He are in 16 g of element?
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
What is the mass in grams of 1.5 moles of helium?
The mass of 1,5 moles of helium is 6,003 903 g.
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 are present in 205g 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.
What is the mass of 5 moles of he atoms?
5 moles of helium He atoms is equivalent to 20,013 g.
How many moles are contained in 1.23 grams of krypton?
# moles = mass / molar mass = 1.23g / 83.80g/mol =1.47x10^-2 moles There are 1.47x10^-2 moles in 1.23g of krypton
Is it false that the mass of 2 moles of helium is 8 grams?
No it is true. 1 mole of helium is 4 g. So 2 moles will be 8 g.
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How many moles of He are in 16 g of element?
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
A balloon has a volume of 6.3 liters Calculate the mass of helium that it would take to fill the balloon?
The mass of helium contained will be 1 gram.
How many moles are present in 40g of helium?
4 g of helium is equivalent to 1 mole of helium
