A sample ofNaClO3is converted by heat toNaClwith a loss of0.16 gof oxygen. The residue is dissolved in water and precipitated asAgCl. The mass ofAgCl(ing) obtained will be: (Given: Molar mass ofAgCl=143.5 g mol-1)

Options:

Answer:
D
Solution:

2NaClO32NaCl+3O2
2 moles of NaCl=3 moles of oxygen
nNaCl=0.1632×23=1200×23=1300
The number of moles ofNaCl=The number of moles ofAgCl
1300=nAgCl
Weight ofAgCl=1300×108+35.5=1300×143.5
=0.48 g
