Question

Given the formula for the gas law: pv = nrt. katie tried to solve for the v variable in order to solve a problem. she rearranged the formula so that v = pnrt. determine if katie solved the equation correctly. if not, describe what mistake she made and solve the equation for v and justify your steps.

Answer 1

Katie made a mistake. P = (nRT)/P is the correct equation, not V = PnRT

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
