What is the molarity of a solution containing 100 moles of NaCl dissolved in 10 liters of water?
A. 2 mol/L
B. 5 mol/L
C. 0.5 mol/L
D. 10 mol/L

So- I don't know the equation for this, if anyone knows the equation could you put it down below? I can get the answer, but my notes are just.. all over the place and I cannot find the specific equation in 100 other equations I have on my desk. Thank you!

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

10 years is the answer
