V rms = root mean square velocity = (3*R*T/M) 1/2 , Units: m/s R is the ideal gas constant, T is the temperature, and M is the molar mass.

Vrms = root mean square velocity = (3*R*T/M)1/2, Units: m/s

R is the ideal gas constant, T is the temperature, and M is the molar mass.

In the end, the units of the above formula should equal m/s to match the desired units of Vrms

Below are a few options of units for T, R, and M. Knowing that 1 J = 1 kg*m2/s2, which of the below units should you use in the formula for Vrms to result in final units of m/s?

Temperature: 1) oC or 2) K

R: ideal gas constant as 1) 0.08206 L*atm/(mol*K), 2) 8.314 J/(mol*K)

M: molar mass in 1) g/mol, 2) kg/mol

Enter a three digit number below of the correct set of units based on the above. For example, If you believe your temperature should be in K, R should be L*atm/(mol*K), and M should be g/mol, enter 211 in your clicker.
