Hello, in this question, we are given this balanced equation.
00:06
I have omitted the states of matter in this equation because they are not needed for what we're using the equation for.
00:13
What we are using the equation for is the mole ratio.
00:16
The mole ratio tells us the ratio in which the reactants react and the products are formed.
00:22
The mole ratio comes from the coefficients in this balanced equation.
00:26
So what this equation is telling us is that for every three moles of no2, we'll react one mole of water.
00:37
And i knew that was a one because anytime a coefficient is not written in front of a term, it's understood that it's a one, just like a math class.
00:47
All right, and that produces the products in a two -mole to one -mole ratio.
00:55
So this is the ratio, which the reactants and then form the products.
00:59
In this question, we want to produce 6 .49 moles.
01:06
Let me change colors.
01:07
Here.
01:07
Hold on.
01:09
All right.
01:09
We want to produce 6 .49 moles of the h .n .03.
01:16
And we want to know how many moles of n .o2 would be required to do this, assuming we have plenty of water available...
