Explanation / Answer

5. formula is C3H503NS, THE MOLECULAR MASS= 3X12.01+5X1.008+3X12+14+32.07=135.14g

ans: E, 135.14

6.FORMULA C17H19NO3, THE MOLECULAR MASS= (12X17)+19X1+14.01+3X16= 285.3 g

ANS: B 285.3g

7. ans is A, C4H8N204 HAS 148 g of molecular weight

8. particals in one mole of substace, ans A

9. ANS A, 47/101.96=0.46 MOLES

2. 2NaN3= 2Na+3N2, IT IS DECOMPOSITION REACTION
