2NaIO3+5NaHSO3reacts and give 3NaHSO4+2Na2SO4+H2O+I2.

Question

If you wish to prepare 1.00kg of I2, what mass of NaIO3 is required? what mass of NaHSO3?

Answer 1

figure the moles of I2 represented by a mass of 1kg. Then, looking at the coefficents, you must need twice that number of moles of NaIO3. Convert that to mass.
