Question

Which of the following mathematical expressions correctly evaluate the specified type of molecular speed for an ideal gas? (Assume $P$ = pressure, $d$ = density, $R$ = universal gas constant, $M$ = molar mass).

Prashant Kotian · Accepted Answer

Correct answer: A,B,C,D. All formulas are correct. Options A, B, and C are the standard speed formulas from KTG. Option D is derived from the ideal gas density formula . Substituting this into the formula yields .
