How to Calculate the Volume of Gas at STP?

What is the ideal gas law equation used to calculate the volume of gas at STP?

A. PV = nRT

B. V = nRT/P

C. PV = nT

D. V = RT/P

Answer:

The correct equation to calculate the volume of a gas at STP is B. V = nRT/P.

When dealing with gases at STP (Standard Temperature and Pressure), the ideal gas law equation is crucial to determine the volume of the gas. The equation to use in this scenario is V = nRT/P, where V represents the volume, n is the number of moles of the gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure.

In the given scenario where we have 3.33 moles of fluorine gas at STP, the volume can be calculated using the ideal gas law equation. By plugging in the values for n, R, T, and P, we arrive at the final answer of 74.6 liters for the volume of gas.
