What is the most probable speed of oxygen gas with the mass of 32 gram

1.	What is the most probable speed of oxygen gas with the mass of 32 grams at 27-degree centigrade?(a) 33.74 m/s(b) 44.78 m/s(c) 57.94 m/s(d) 549.14 m/sThe question was asked by my school teacher while I was bunking the class.Origin of the question is States of Matter in chapter States of Matter of Chemistry – Class 11
Answer» Right answer is (B) 44.78 m/s Explanation: The FORMULA for the most probable speed of a gas is given as \(\sqrt{8RT/πM}\). Here R is a universal gas constant which is ALWAYS EQUAL to 8.314 kgm^2s^-2, T=300 Kelvin and M = 0.032 kg So by substituting, we GET an answer as 44.78 m/s.
