How many moles are present in 40g of helium?
4 g of helium is equivalent to 1 mole of helium
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
How do you convert 26.7kg of helium into moles of helium?
6675 moles Moles = weight (in g) / atomic weight = 26700 g / 4 = 6675 moles
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 in 30.8g of helium?
4 g of He = 1 mole. So, 30.8 g = 7.7 moles
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
0.46 divided by the formula weight of helium (4) 0.46/4=0.115 or 0.12 moles 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 6.46 g of Helium?
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
How many moles are present in 40g of helium?
4 g of helium is equivalent to 1 mole of helium
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
How do you convert 26.7kg of helium into moles of helium?
6675 moles Moles = weight (in g) / atomic weight = 26700 g / 4 = 6675 moles
How many moles are in 30.8g of helium?
4 g of He = 1 mole. So, 30.8 g = 7.7 moles
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?
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
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 in 978 g Ca?
978 g calcium contain 24,4 moles.
How many moles are present in 0.12g of helium?
1 mole He is 4.0 g. Use as a conversion factor to change 0.12 g He to moles.
