Answer:

P = 29,523 kPa

Step-by-step explanation:

The formula of the Ideal Gas Law is:

PV = nRT

In this formula,

P = pressure (kPa)

V = volume (L)

n = number of moles

R = 8.314 (L*pKa/mol*K)

T = temperature (K)

You have been given values for all of the variables but pressure. Therefore, you can plug the given values into the equation and simplify to find pressure.

PV = nRT

P(1 L) = (13 moles)(8.314 L*kPa/mol*K)(273.15 K)

P(1 L) = 29523

P = 29,523 kPa

**I am pretty certain my math is correct. I also checked with an ideal gas law calculator and got this same answer. Either I am missing something or some of the values are wrong. Hopefully this explanation helps clear something up though.**
