35. ammonium perchlorate, nh co., is a common fuel component of solid fuel rockets. if 75% of the oxygen in nh. co. was converted to molecular oxygen, how many grams of molecular oxygen would be produced from 117.5 kg ammonium perchlorate? (atomic weights in amu: n = 14.01, ci = 35.45, 0 = 16.00, h = 1.008) a. 4.8 x 10^g 02 b. 6.4 x 10^g 02 c. 2.2 x 10^g 02 d. 2.4 x 10^g 02

The mass of molecular oxygen produced is

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of ammonium perchlorate = 117.5 kg = 117500 g     (Conversion factor:  1 kg = 1000 g)  

Molar mass of ammonium perchlorate = 117.5 g/mol

Putting values in equation 1, we get:

The chemical equation for the decomposition of ammonium perchlorate follows:

By Stoichiometry of the reaction:

2 moles of ammonium perchlorate produces 3 moles of molecular oxygen

So, 1000 moles of ammonium perchlorate will produce = of molecular oxygen

Now, calculating the mass of molecular oxygen by using equation 1, we get:

Molar mass of molecular oxygen = 32 g/mol

Moles of molecular oxygen = 1500 moles

Putting values in equation 1, we get:

Hence, the mass of molecular oxygen produced is
