4.00 L of an ideal gas at 0.817 atm and 39.0 °C is
brought to STP. What is the volume of the gas at
STP?

The volume of the gas at STP is 2.86L

Explanation:

Given:

Volume, V₁ = 4L

Pressure, P₁ = 0.817 atm

Temperature, T₁ = 39°C

                      T₁ = 39 + 273K

                      T₁ = 312 K

At STP,

Pressure, P₂ = 1 atm

Temperature, T₂ = 273 atm

Volume, V₂ = ?

According to the gas law:

On substituting the value, we get:

Therefore, the volume of the gas at STP is 2.86L

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

probably .5
