Tell what the initial pressure of a gas is given the following information: a. V1 = 338L b. P2 = standard pressure (in atm) c. V2 = 294 L

We can use something called Boyle's law. This states that the product of the volume and pressure is constant. This means that we can set the product of initial pressure and volume equal to the product of the final pressure and volume. The equation is:

P1*V1 = P2*V2

We know that:

V1 = 338L

P2 = Standard Pressure 1 atm

V2 = 294L

If we set up our equation, we can solve for P1 as:

P1 = P2*V2/V1

P1 = 1 atm * 294L / 338 L = 0.870 atm

Therefore:

The initial pressure (P1) is 0.870 atm
