Answer:
2.7099×10^19 molecules
Explanation:
At STP,
P = 1 atm = 101325N/m^2, T = 273K
From the ideal gas equation
PV = nRT
n = PV/RT
V = 1cm^3 = 1cm^3 × 1m^3/10^6cm^3 = 10^-6m^3, R = 8.31J/molK
n = 101325×10^-6/8.31×273 = 4.5×10^-5 mole
From Avogadro's law
1 mole = 6.022×10^23 molecules
4.5×10^-5 mole = 4.5×10^-5 × 6.022×10^23 = 2.7099×10^19 molecules

Gravity brings any object “downward” or to the ground. If another force is working on the object, gravity can remain the object to be motionless or when there is no other force it may increase the speed. Or if the object is pulling in another direction, opposite from the pull of gravity then it does have the power to change the direction of the objects motion.
Hope this helps!
Taking what you have learned about Congressional powers and limitations, what similarities are there between how our government works and your own experiences with board game rules? Think of a time when you played a board game such as Sorry, Monopoly, or Pictionary. List five standard enumerated rules for board games like this. For example, the person who rolls the highest number gets to go first. Then list five standard implied rules that all good team players should abide by. For example, no cheating.
The concept of semantic network model of memory states that concepts that are related in meaning are store in the sit of memory closer to each other than concepts that are not so related.
