What is the molecular formula of a compound if its percent composition is 26.43 % Na ,36.78 % S , and 36.78 % O. (Its molar mass is 174 g/mole?
Added by Cristian C.
Step 1
Percent composition of Na = 26.43% Percent composition of S = 36.78% Percent composition of O = 36.78% Assume we have 100 g of the compound, then: - Mass of Na = 26.43 g - Mass of S = 36.78 g - Mass of O = 36.78 g Number of moles of Na = 26.43 g / 22.99 g/mol Show more…
