To two decimal places, what is the relative
atomic mass and the molar mass of the element potassium, k?

The atomic mass of Potassium is 39.09 u+-0.0001u and molar mass is  39.09 g,s/mole

Explanation:

Potassium is a metal belongs to group 1 and period 4 whose atomic number is 19 and electron configuration is 2,8,8,1.

The molar mass of Potassium or K is 39.09 g,s/mole and the atomic mass is 39.09 u+-0.0001u. Potassium was first discovered by Humphrey Davey and was first found in the ashes of plants. It also occurs in the mineral sylvite or KCL and is mined as such.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
