#In chemistry, the ideal gas law states:
#
# pressure * volume = # of moles * gas constant * temperature
#
#This is usually abbreviated to:
#
# PV = nRT
#
#We can solve this for any of these five variables, but let's
#solve it for Pressure. In terms of Pressure, the ideal gas
#law states:
#
# P = (nRT) / V
#
#Write a function called find_pressure that takes as input
#three variables: number of moles, temperature, and volume.
#You can call these variables in the function whatever you
#want, but they must be specified in that order: moles, then
#temperature, then volume. You should assume all three are
#floats. Then, return as output your calculation for
#pressure. For the gas constant, you should use the value
#0.082057.
#
#Hint: Python's rounding errors can change based on the
#order of the multipliers. If you're having difficulty with
#your answer being off by tiny fractions, change the order
#of the numbers to match the order in the formula above.


#Write your function here!
def find_pressure(n, T, V, test_R):
#R = 62.364/760
pressure = (n*T*test_R)/V
return pressure


#Below are some lines of code that will test your function.
#You can change the value of the variable(s) to test your
#function with different inputs.
#
#If your function works correctly, this will originally
#print: "Result: 48.905972000000006". The extra zeroes and
#the 6 are rounding errors by Python.
