#6 should be the independent variable because that's the one you can control
Answer:
Pf= 190 mmHg
Explanation:
(Pi×Vi)/Ti = (Pf×Vf)/<em>T2</em>
Initial Pressure Pi = 756mmHg,
Initial Volume Vi = 2L,
Initial Temperature Ti = 0°C=273K
Final Pressure Pf = ?,
Final Volume Vf = 2L+ Vi = 4L,
Final Temperature <em>T2</em>= 137K
Pf = (Pi × Vi × T2 )/(Vf × Ti)
Pf = (756 × 2 × 137)/(4 × 273)
Pf = 189.7 mmHg
Pf <em>approx.</em> 190mmHg
Given the amount of gas, temperature and volume , the pressure of the gas is approximately 41.7atm.
<h3>What is Ideal Gas Law?</h3>
The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given the data in the question;
- Temperature T = 305K
- Volume of the gas V = 3.0L
PV = nRT
P = nRT / V
P = ( 5mol × 0.08206 Latm/molK × 305K ) / 3.0L
P = 125.1415Latm / 3.0L
P = 41.7atm
Therefore, given the amount of gas, temperature and volume , the pressure of the gas is approximately 41.7atm.
