Sodium chlorate decomposes into sodium chloride and oxygen gas as seen in the equation below.

2NaClO3 --> 2NaCl +3O2

How many moles of NaClO3 were needed to produce 7 moles of O2?

Round your answer to the nearest whole number.


I need help with this so bad, otherwise I’m 100% going to fail the quiz, thank you!!

Answer:

4.62

so 5

the ratio is 2 na chlorates for 3 O2 so multiply 7 by 2/3

Explanation:

Oseni

The number of moles of  NaClO3 that would be needed to produce 7 moles of O2 would be 5 moles of NaClO3 approximately.

Stoichiometric calculations

From the equation of the reaction:

2NaClO3 --> 2NaCl +3O2

The mole ratio of NaClO3 to O2 is 2:3.

Thus, every 3 moles of O2 require 2 moles of NaClO3 .

7 moles of O2 will, therefore require:

                                     = 2 x7/3

                                              = 4.6666 moles of NaClO3

To the nearest whole number = 5 moles of NaClO3
