Before you can identify how much you need, first you need to solve and write the equation.
You need to know first that you need to convert grams of ZnO --> moles of ZnO
= 358.5 g ZnO x 1 mol ZnO / 81.39g ZnO
Solve and it will give you = 4.40 mol of ZnO
Next, multiply the answer above to 1 mol O2 / 2 mol ZnO
It will give you the answer of 2.20 mol of O2
Multiply the answer above to the molar mass. This will give you the answer of what you’re looking for.
Molar mass: 32
= 2.20 mol O2 x 32g O2 / 1 mol O2
= 70.4g O2
The grams of O2 that are required to produce 385.5 grams of zno is: 70.4 g O2
We have that it can be said that grams of o2 are required to produce 358.5 grams of zno is
From the question we are told
How many grams of o2 are required to produce 358.5 grams of zno??
Generally the equation for the is mathematically given as
Moles of Zno= 358.5 g ZnO x 1 mol ZnO / 81.39g ZnO
Moles of Zno= 4.40 mol of ZnO
Hence
2.20 mol of O2
Where molar mass=32
Therefore
grams of o2= 2.20 mol O2 x 32g O2
