Mass is calculated by using an objects inertia. Since inertia is a quality of matter that resists motion, we can apply an increasing force to an object until it accelerates.
Then, by measuring its acceleration we can now determine its mass using the simple equation F=m×a, except rewritten as m=Fa.
So we divide the force that we applied by the acceleration rate and we get the objects mass.
Without inertia this cannot be done.
∴ Answer is C
Answer:
The answer is 17.03052. We assume you are converting between grams Ammonia and mole.
Answer : It takes time for the concentration to decrease to 0.100 M is, 22.4 s
Explanation :
Formula used to calculate the rate constant for zero order reaction.
The expression used is:
![\ln [A]=-kt+\ln [A_o]](https://tex.z-dn.net/?f=%5Cln%20%5BA%5D%3D-kt%2B%5Cln%20%5BA_o%5D)
where,
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial concentration = 0.537 M
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= final concentration = 0.100 M
t = time = ?
k = rate constant = 0.075 M/s
Now put all the given values in the above expression, we get:
Therefore, it takes time for the concentration to decrease to 0.100 M is, 22.4 s

production and use of chlorofluorocarbons (CFCs) is that lower levels of ozone
allowed more ultraviolet radiation to reach Earth. CFC is an organic compound
which is used refrigerants, propellants and solvents.</span>
Answer:
3,32e-14 moles
Explanation:
We use the number of Avogadro:
6,02e23 molecules-------1 mol
2e10molecules------------X =2e10/6,02e23= 3,32x-14 moles
