## anonymous one year ago Medal and fan reward I KNOW HOW TO WORK THIS OUT, I JUST WANT THE ANSWER (i'm just double checking to see if I'm right or not) a) If a sample containing 2.00 mL of nitroglycerin (density= 1.592 g/ml) is detonated, how mahy total moles of gas are produced? b) If each mole of gas occupies 55 L under the conditions of the explosion, how many liters of gas are produced? c) How many grams of N2 are produced in the detonation?

your*

3. anonymous

a) .102 b) 5.59 c) .437 (a friend of sort of helped me with it)

4. anonymous

@Shalante what u get?

5. anonymous

Yes that is correct!

6. anonymous

wait PLEASE @Shalante can you PLEASE explain to me how you got letter c

7. anonymous

Yes Grams of nitroglycerin is 3.184grams Molar mass of nitroglycerin is 227g/mol There are 6 moles of N2 for every 4 mols of nitroglycerin (C3H5N3O9) N2 molar mass is 28g/mol

$\frac{ 3.184g C _{3}H _{5}N _{3}O _{9} }{ 1} \times \frac{ 1mol C3H5N3O9 }{ 227g C3H5N3O9 } \times \frac{ 6mol N2 }{ 4mol C3H5N3O9 } \times \frac{ 28.00g N2 }{ 1mol N2 }$

when I did that I got .58

Detonation of nitroglycerin reaction $4C _{3}H _{5}N _{3}O _{9}\rightarrow 12CO _{2}+ 6N _{2}+O _{2}+10H _{2}O$

11. anonymous

Lemme see.

12. anonymous

but when I multiplied I got .589 @ Shalante what am I doing wrong

13. anonymous

@Shalante

14. anonymous

Gimme a second.

15. anonymous

K THANKS! YOU'RE THE BEST

16. anonymous

Actually it is 0.58. I am right.

17. anonymous

18. anonymous

oh ok then

19. anonymous

I trust you

20. anonymous

Haha, I am glad you told me to show you the steps.

21. anonymous

The dimensional analysis looked close between 0.30-0.7 so I assumed you got it right. Thats is actually better for me to do it than check it lol.

22. anonymous

lol and for b it's just 55L times the answer I got for a right?

23. anonymous

Yeah because they to want to know the number of moles with a different amount of liter.

24. anonymous

all right thx

25. anonymous

No problem! I need to sleep now. Good luck with the rest
