Question

inc Oxide is a substance found in creams that are used to treat minor skin irritations such as diaper rash, burns and cuts. It forms when solid zinc reacts with oxygen gas according to the balanced equation below:
2Zn + O₂ --> 2ZnO

If 358.5 grams of ZnO is required to produce 1 tube of diaper rash cream, how many grams of O₂ would be needed to produce each tube?

Expert Solution

Step 1

Well, we will use the balanced reaction and simple mole concept to calculate the mass of O₂ required.

We will require the molar masses of-

O₂=32 ^g/_mol

ZnO=81.38^g/_mol
