The concentration can be expressed as the quotient between the masses.

<h3>How to express the concentration?</h3>

We define the concentration (of something) in a solution, as the amount of that thing that there is in the solution.

With that in mind, the concentration can be defined by the quotient between the mass of the particular thing and the mass of the solution.

For example, in a mix of water and salt, the concentration of salt would be given by the quotient between the mass of salt and the total mass of the mix.

Answer:

The calculation and filling of the table based on the ratio indicated by the column is shown on the second uploaded image

1 This is True

2 This is False

3 This is False

4 This is True

5 This is True

Explanation:

Based on your calculations, indicate whether each statement is True (T) or False (F):

Considering the first statement

Looking at the question we can see that the first statement is TRUE this because all the three experiment have different initial concentration (3.5,3.0 & 2.6)

Considering the second statement

Looking at table we can see that the second statement is FALSE because

the ratio value of [NO2]/ [N2O4] in all three experiment have different value 1.4 , 1.5 & 1.7 is not a constant value.

Considering the Third statement

Looking at the table we can see that the third statement is FALSE this is because the ratio value of 2[NO2]/ [N2O4] in all three experiment have different value 2.7, 3.0 & 3.3 is not a constant value.

Considering the Fourth statement

Looking at table we can see that the fourth statement is TRUE this is because the ratio value of $[NO2]^{2}/ [N2O4]$ in all three experiment have same value 3.9, 3.9 & 3.9 is a constant value.
