Answer:
number of moles of 
=4.16mol
Explanation:
experiment data:
temperature= 
=273+22 k=295k
pressure=1.007 atm
volume is missing so assuming volume-=100L
using ideal law relationship
ideal gas means gas which occupies negligible space and there is no interaction between the molecules of gases.
PV=nRT
put all the experimental data, we get
n=4.15 mol
number of moles of =4.16mol
Here first we will identify the number of significant figures in the given two dimensions
2.3mm : there are two significant numbers
8.00mm: there are three significant numbers
so we will report the answer to minimum number of significant number , which is two
the answer is 18.4
We will report it to be 18 mm^2
The speed of the horses in this carousel is constant, but the horses are accelerating because their direction is changing constantly. Acceleration toward the center of a curved or circular path is called centripetal acceleration.
