if exactly 59.6g of dinitrogen monoxide are needed to inflate your air bag to the correct size, how many grams of NH4NO3 would you need to decompose?

Respuesta :

108.05 grams of NH4NO3 would you need to decompose to inflate your air bag to the correct size with 59.6g of dinitrogen monoxide.

Explanation:

Data given:

mass of dinitrogen  monoxide = 59.6 grams

atomic mass of dinitrogen monoxide = 44.01 grams/mole

grams of N[tex]H_{4}[/tex]N[tex]O_{3}[/tex]  = ?

atomic mass of ammonium nitrate = 108.05 grams/mole

balanced chemical equation:

N[tex]H_{4}N_{} O_{3}[/tex][tex]N_{2}[/tex]O +2 [tex]H_{2}[/tex]O

Firstly the number of moles will be calculated from the given mass by using the formula:

number of moles = [tex]\frac{mass}{atomic mass of 1 mole}[/tex]

putting the values in the equation:

number of moles = [tex]\frac{59.6}{44.01}[/tex]

number of moles = 1.35 moles

from the balanced equation :

1 mole of ammonium nitrate decomposes to release 1 mole of dinitrogen monoxide

so, 1.35 moles will give 1.35 moles of dinitrogen  monoxide.

mass = atomic mass x number of moles

mass = 80.043 x 1.35

mass = 108.05 grams of ammonium nitrate.
