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:
$V_f = \frac{p_i V_i}{p_f} = \frac{(1.52 \cdot 10^5 Pa)(0.005 m^3)}{1.65 \cdot 10^5 Pa} =0.0046 m^3 = 4.6 L$

Manuel traveled 3 hours nonstop to Mexico, a total of 197 miles. He took a train part of the way, which averaged 70mph, and t

Anton [14]

Answer:

1.7 hours

Explanation:

Time taken in the journey = 3 hours

Distance of the entire journey = 197 miles

Distance travelled on train = x

Distance travelled on bus = 197-x

Average speed of train = 70 mph

Average speed of bus = 60 mph

Time = Distance / Speed

$\frac{x}{70}+\frac{197-x}{60}=3\\\Rightarrow \frac{6x+1379-7x}{420}=3\\\Rightarrow -x+1379=3\times 420\\\Rightarrow -x=1260-1379\\\Rightarrow x=119\ miles$
