The ratio of equivalent Li2O to eq. Na2O is 0.33 to 1 (by mass). What will be the molar ratio of Li:Na?
Answer:
Find the molecular masses of Li2O and Na2O
Molecular mass of Li2O = 14+16=30 grams/mole
Molecular mass of Na2O = 46+16 = 62 grams/mole
So, the ratio of molecular weights = 30:62 = 15:31
Dividing the mass ratio by this ratio, we get the molar ratio of the 2 species :
(0.33/15) : (1/31) = (31*0.33):(15) = 10.23 : 15
It is approximately equal to 2:3
