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.
What is the key conversion factor needed to solve all stoichiometry problems?
Moles
How is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
How many moles of sodium are in 4.0 moles of NaCl?
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
What are two forms of the conversion factor that will convert one mole to number of objects and number of objects to one mole?
One mole is equivalent to 6.022x10^23 atoms. Which is also known as Avagadro's number. For example if you have 46 gms of sodium. The number of sodium atoms is 2x6.022x10^23. This is because we have two moles of sodium. (Molar mass of sodium is 23 grams per mole.)
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.
What quantity serves as the conversion factor between the mass of a sample and how many moles the sample contains?
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
How many moles are there in 17.5 grams of sodium?
11.5 g of Na times x (1 mole of Na/22.99 g of Na) = 0.500 mol of Na I suppose the conversion factor would be what's in parenthesis.
What conversion does the value of the conversion factor depend upon the formula of the substance?
mass of any substance to moles
What is the key conversion factor needed to solve all stoichiometry problems?
Moles
How is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
How many moles of sodium are in 4.0 moles of NaCl?
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
How many moles of sodium in 6.5 gram of sodium?
The answer is 0,111 moles.
How many moles are there in 2.50 moles of sodium?
Sodium in its elemental form is just sodium metal, Na. Thus assuming that the sample of sodium is pure, there are 2.50 moles of sodium in a 2.50mol sample.
What are two forms of the conversion factor that will convert one mole to number of objects and number of objects to one mole?
One mole is equivalent to 6.022x10^23 atoms. Which is also known as Avagadro's number. For example if you have 46 gms of sodium. The number of sodium atoms is 2x6.022x10^23. This is because we have two moles of sodium. (Molar mass of sodium is 23 grams per mole.)
When calculating the number of moles of solid Na2SO4 the factor used is?
The molar mass of anhydrous sodium sulfate is 142,04.
