Answer:
His speed was 2 m/s, and his velocity was 0
Explanation:
In physics, speed of an object is defined as the change in position with the change in its time. While velocity may be defined as the change in the position of the body with respect to the time taken.
Speed in a scalar quantity which means it has only magnitude while velocity has both magnitude and direction.
To determine change in velocity both direction as well as magnitude has to be changed.
In the context, Kai was 200 m of the library in the north direction. Now for the round trip to the library and back to his position, Kai took 200 seconds time to cover the distance.
So for the round trip, the speed of Kai would be 2 m/s abut the velocity of Kai is 0 as the displacement of Kai is 0.

These are steps to convert from grams of gas to liters of a gas:
find the molar mass from the formula.
find moles by dividing given mass to molar mass.
find the volume by multiplying the number of moles to molar volume.
