Answer:

This question begins with something, you should know: molar mass from water is aproximately 18 g/m, so if 18 grams of water are contained in 1 mole, the 40 grams occuped 2.22 moles. As you see, opcion a is the best!

According to Graham's Law of Diffusion," Diffusion of Gas is inversely proportional to square root of its Molecular Mass or Density".

                          rᵇ/rᵃ  =  \sqrt{da/db}
Or,
                          rᵇ/rᵃ  =  \sqrt{Ma/Mb}     ----- (1)
As, 
                          Ma  =  275 g/mol

                          Mb  =  205 g/mol

Putting Values in eq.1,

                          rᵇ/rᵃ  =  \sqrt{275/205}

                          rᵇ/rᵃ  =  1.15

Result:
          Perfume B will diffuse 1.15 times faster than Perfume A. Hence, Perfume B will be first smelled by the person.

Which of the following affects the speed of a seismic wave?
scoray [572]

Explanation:

The speed of seismic waves is affected by the density of the underlying rock.

Seismic waves are elastic waves that transmits elastic energy from one point to the other.

These waves generally produced during an earthquake.

  • The higher the density of rock bodies, the faster the wave travels.
  • Rocks that are well packed with little to no void have a higher seismic velocity.
  • Where density of rock is low, the speed is also low
