Answer :
The molar mass is 64.1 g/mol.
Solution:
(Velocity)² = 3RT/M
M = 3RT/(velocity)²
= 3x8.3145J/k.mol x 350k/(369m/s)²
= 0.0641 kg/mol.
Molar mass = 64.1 g/mol
Average velocity is a measure of total displacement divided by total time. The total displacement is the distance between the start and endpoints. Since the car moves from point A at both the start and end points the total displacement is zero and the average velocity is also zero.
Velocity is the distance traveled per unit of time, the speed of movement. The speed of a car traveling on a smooth, flat section of a highway without traffic congestion is constant and not zero. Acceleration is the rate of change of velocity. The reason is simple. Velocity is the percentage of time an object moves along a path and Velocity is the speed and direction of an object's movement.
