Well Sodium Selenide has a formula of Na2Se. Let's take a look at their molecular masses
Molecular Mass of Sodium = 22.99
=> 2 Sodiums = 45.98g
Molecular Mass of Selenide = 78.96
=> The Total Molecular Mass is 45.98 + 78.96 = 124.94 g mol-1
What does that figure mean?
This is the amount of Sodium Selenide that is required to make a 1 mole solution of this substance in a litre of water.

How many moles are in sodium carbonate?
To calculate the number of moles in sodium carbonate, you need to know the mass of the substance and its molar mass. Once you have the mass, divide it by the molar mass of sodium carbonate (105.99 g/mol) to find the number of moles. For example, if you have 10 grams of sodium carbonate, you would have 0.094 moles (10 g / 105.99 g/mol).
How many moles of sodium carbonate were present in 2 grams of hydrated sodium carbonate?
To determine the number of moles of sodium carbonate in 2 grams of hydrated sodium carbonate, we first need to calculate the molar mass of Na2CO3·xH2O. Once we have the molar mass, we can use the formula: Moles = Mass / Molar mass. Given that hydrated sodium carbonate has the molar mass of Na2CO3·xH2O, we can determine the number of moles in 2 grams of the compound.
What is the molar mass of lithium selenide?
The molar mass of lithium selenide (Li2Se) can be calculated by adding the atomic masses of lithium and selenium together. The atomic mass of lithium is approximately 6.94 g/mol, and the atomic mass of selenium is approximately 78.97 g/mol. Therefore, the molar mass of lithium selenide is approximately 163.85 g/mol.
