Answer:
Katie made a mistake. P = (nRT)/P is the correct equation, not V = PnRT
Step-by-step explanation:
The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the moles of gas, R is the gas constant, and T is the temperature, in Kelvin.
Solving for V:
PV = nRT
V = (nRT)/P
Katie did not solve the equation corretly. To move V from the left to the right side of the equation, she needed to divide both sides by P:
PV = nRT
PV/V = (nRT)/P
P = (nRT)/P is the correct equation
