Question

How many liters of water vapor are produced if 75 L of oxygen is reacted with excess hydrogen at STP?

Answer 1

Start by finding the moles of O.

Answer 2

O being oxygen.

Answer 3

When you work with \(\sf\color{blue}{ideal}\) gases you don't have ton convert back and forth. So, start by writing an equation for reaction in your question.

Btw, oxygen gas exists as \(O_2\).

Answer 4

So after I turn it to moles, what do i do next

Answer 5

Now use mole ratio to find the moles of H20. What is the ratio of oxygen to water?
