2.04gms of sodium,no of moles= 2.04/gmw of sodium no of moles of carbon=2.65*10^22/avagadro number 0.132moles of oxygen

3. mekaprasantho

give me the above results i will tell the next step

4. mekaprasantho

only if you dont know how to do this problem

5. goformit100

Sir I don't know

6. mekaprasantho

r u an indian

7. goformit100

Yes

8. mekaprasantho

iam from iit kanpur

9. mekaprasantho

nd you

10. mekaprasantho

have you calculated the values

11. goformit100

Prasanth Chanti which branch.

I am preparing for MIT

14. mekaprasantho

k values first we'll introduce ourselves later

i have passed 12th this year

18. mekaprasantho

no of moles sodium=0.088 carbon=0.044 oxygen=0.132

19. mekaprasantho

so mole ratio is 2:1:3

20. goformit100

ok.

21. mekaprasantho

empirical formula is Na2 C O3 sodium carbonate
