Question

A sample of HNO3 contains twice as many atoms as there are ions in 6.846g of Al(SO4)3. Calculate the mass of the HNO3 in the sample.

Answer 1

Answer:

For 100 moles each of sodium atoms and ions there would be a difference of 100 moles of electrons. Mass of 100 moles of electrons= 5.48002 g. Mass of 1 mole of electron = 5.48002 / 100 g . Mass of one electron = 5.48002 /100 × 6.022 ×10 23 = 9.1 ×10 28 g = 9.1×10-31 kg. 28. Cinnabar (HgS) is a prominent ore of mercury.
