22.57% sulfur, 45.06% oxygen and the remaining element as sodium. What is the total number of moles of sodium that is present in the salt if the salt product weighs 5.831g?
First, we need to calculate the molar mass of the salt.
The molar mass of sulfur (S) is 32.06 g/mol.
The molar mass of oxygen (O) is 16.00 g/mol.
The molar mass of sodium (Na) is 22.99 g/mol.
So, the molar mass of the salt = (0.2257*32.06) + (0.4506*16.00) + (0.3237*22.99) = 19.78 + 7.21 + 7.46 = 34.45 g/mol
Next, we need to find the number of moles of the salt in 5.831g.
Number of moles = Mass / Molar mass
Number of moles = 5.831g / 34.45 g/mol = 0.1691 mol
As 0.2257 moles of the salt contains 1 mole of sodium, we can calculate the number of moles of sodium in 0.1691 moles of the salt.
Number of moles of sodium = 0.1691 mol * (1 mol Na / 0.2257 mol salt) = 0.7488 mol
Therefore, the total number of moles of sodium in 5.831g of the salt is 0.7488 mol.
