Science experiments usually include an independent variable, dependent variable, and control. ... Science experiments also include something called constants. A constant is the part that doesn't change during the experiment.
Answer : The final volume will be, 84.4 mL
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,
= initial pressure = 760 torr
= final pressure = 120 kPa = 900 torr (1 kPa = 7.5 torr)
= initial volume = 100 mL
= final volume = ?
Now put all the given values in the above equation, we get:


Therefore, the final volume will be, 84.4 mL
Answer:
V = 177.4 L.
Explanation:
Hello there!
In this case, since this gas can be assumed as ideal due to the given data, we can use the following equation:

Thus, by solving for volume we obtain:

So we can plug in the temperature in Kelvins (537 K), the pressure in atmospheres (0.404 atm) and the molar mass (54 g/mol) to obtain:
