Question

ideal gas law
charles law
boyles law
combined gas law
which law helps us find the moles of gas in a sample?

Explanation:

The Ideal Gas Law formula is \(PV = nRT\), where \(n\) represents the number of moles of gas. By rearranging the formula to \(n=\frac{PV}{RT}\), we can calculate the moles of gas when pressure (\(P\)), volume (\(V\)), temperature (\(T\)), and the gas constant (\(R\)) are known. Charles's Law (\(V_1/T_1 = V_2/T_2\)) relates volume and temperature. Boyle's Law (\(P_1V_1 = P_2V_2\)) relates pressure and volume. The Combined Gas Law (\(P_1V_1/T_1 = P_2V_2/T_2\)) combines pressure, volume, and temperature relationships. Only the Ideal Gas Law directly includes the number of moles (\(n\)) in its formula.
