The pressure of 5.0 l of gas increases from 1.50 atm to 1240 mmhg. what is the final volume of the gas, assuming constant temper
garik1379 [7]
First we need to convert everything into SI units.

The initial volume of the gas is (keeping in mind that 1 L = 0.001 m^3:
V_i = 5.0 L = 0.005 m^3

The initial pressure of the gas is (keeping in mind that 1 atm = 1.01 \cdot 10^5 Pa:
p_i = 1.50 atm=1.52 \cdot 10^5 Pa

The final pressure of the gas is (keeping in mind that 760 mmHg = 1 atm=1.01 \cdot 10^5 Pa)
p_f = 1240 mmHg = 1.65 \cdot 10^5 Pa

At constant temperature, the product between pressure and volume of the gas is constant, so we can write
p_i V_i = p_f V_f

from which we find the final volume of the gas:
V_f =  \frac{p_i V_i}{p_f} = \frac{(1.52 \cdot 10^5 Pa)(0.005 m^3)}{1.65 \cdot 10^5 Pa} =0.0046 m^3 = 4.6 L
