Question

Determine the pressure of the gas trapped in the apparatus shown below when the atmospheric pressure is 695 mmHg. 
A)45 mmHg 
B)650 mmHg 
C)695 mmHg 
D)740 mmHg 
E)760 mmHg

Quizplus · Accepted Answer

The total pressure in the apparatus is the sum of the pressure due to the trapped gas and the atmospheric pressure. Using the formula P_total = P_gas + P_atm, we can solve for P_gas by rearranging the equation to P_gas = P_total - P_atm. Plugging in the given values, we get P_gas = (1435 mmHg) - (695 mmHg) = 740 mmHg. Therefore, the pressure of the trapped gas is 740 mmHg.
