Question

Chemistry: Gas Laws Problems!

Answer 1

Answer : The final volume at STP is, 1000 L

Explanation :

According to the Boyle's, law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.

$P\propto \frac{1}{V}$

or,

$P_1V_1=P_2V_2$

where,

$P_1$ = initial pressure = 1520 mmHg = 2 atm    (1 atm = 760 mmHg)

$P_2$ = final pressure at STP = 1 atm

$V_1$ = initial volume = 500.0 L

$V_2$ = final volume at STP = ?

Now put all the given values in the above formula, we get:

$2atm\times 500.0L=1atm\times V_2$

$V_2=1000L$

Therefore, the final volume at STP is, 1000 L
