a sample of 3 mol of diatomic gas is measured to have a temperature of 300
k. if the mass of the gas is 0.048 kg, what is the approximate average speed
of the molecules in the gas? (recall that the equation for kinetic energy due
to translation in a gas is ketranslational -
= mv2 = nrt, and r= 8.31 j/(mol.

o a. 612 m/s
o b. 684 m/s
o c. 608 m/s
o d. 670 m/s
