Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.

A sample of an ideal gas has a volume of 2.31 l at 287 k and 1.10 atm. calculate the pressure when the volume is 1.45 l and the

Hello!

The pressure of the Ideal Gas when the volume is 1,45 L and the temperature is 298 K is 1,82 atm.

To solve this problem we need to apply the Ideal Gas Law for the initial conditions and the final ones, clearing the equation for the number of moles (n) and the ideal gas constant (R) which remain constant:

$P_n*V_n=n*R*T_n \\ \\ n*R= \frac{P_n*V_n}{T_n}$

Now we match n*R for the initial conditions (1) and the final ones (2), clearing the equation for P₂

$\frac{P_1*V_1}{T_1}= \frac{P_2*V_2}{T_2} \\ \\ P_2= \frac{P_1*V_1*T_2}{T_1*V_2}= \frac{1,10 atm*2,31 L *298 K}{287K*1,45 L}=1,82 atm$

Have a nice day!
