Question

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?

Answer 1

What are you answers?

Answer 2

your*

Answer 3

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

Answer 4

@Shalante what u get?

Answer 5

Yes that is correct!

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

when I did that I got .58

Answer 10

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

Answer 11

Lemme see.

Answer 12

but when I multiplied I got .589 @ Shalante

what am I doing wrong

Answer 13

@Shalante

Answer 14

Gimme a second.

Answer 15

K THANKS!

YOU'RE THE BEST

Answer 16

Actually it is 0.58.
I am right.

Answer 17

Your friend was wrong.

Answer 18

oh ok then

Answer 19

I trust you

Answer 20

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

Answer 21

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.

Answer 22

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

Answer 23

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

Answer 24

all right thx

Answer 25

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