Answer:
22.5
Explanation:
all you have to do is take the number of moles of al and multiply them by sulfuric acids mole ratio as given in the equation (3), then divide by aluminums mole ratio number (2). then you will have moles of sulfuric acid.
*note: this only works if you are going moles to moles, if you are converting to anything else, this will NOT work*

From the pair of values given, the ratio of the volume to the temperature for the first data pair is, 0.0026 cm³/K
<h3>What is a Ratio?</h3>
A ratio is a comparison between two quantities showing how much one quantity differs from another.
From the data given, the first data pair is as follows ;
- Temperature = 276 K
- Volume = 0.72 cm³
Ratio of volume to temperature = volume / temperature
Ratio = 0.72 / 276
Ratio = 0.002608 cm³/K
The significant figure's rule for division is the least number of significant figures used in the operation.
The least significant figure of the values given is 2.
Therefore, the ratio of the volume to the temperature for the first data pair is 0.0026 cm³/K
