Since the temperature is constant, therefore, this problem can be solved based on Boyle's law.
Boyle's law states that: " At constant temperature, the pressure of a certain mass of gas is inversely proportional to its pressure".
This can be written as:
P1V1 = P2V2
where:
P1 is the initial pressure = 1 atm
V1 is the initial volume = 3.6 liters
P2 is the final pressure = 2.5 atm
V2 is the final volume that we need to calculate
Substitute with the givens in the above mentioned equation to get the final volume as follows:
P2V1 = P2V2
1(3.6) = 2.5V2
3.6 = 2.5V2
V2 = 3.6 / 2.5 = 1.44 liters
The variables to control in an experiment to determine the effect of different fertilizers on the rate of plant growth include soil composition, temperature, water, and light.
<h3>What are controlled variables?</h3>
The expression controlled variables makes reference to experimental conditions that must be equal or constant between experimental groups in order to obtain better comparisons when collecting results.
In conclusion, The variables to control in an experiment to determine the effect of different fertilizers on the rate of plant growth include soil composition, temperature, water, and light.

Answer:
5.00g
Explanation:
Molarity is moles per liter
Therefore:
x moles/.250L = .5 moles/1L
Solve for x: .125 moles required
Question asks for grams of NaOH so multiply the moles by the molar mass of NaOH
.125(39.997) = 4.999625g
Rounds to 5.00g
