Intensity I of a sound wave is defined as I = P A Assume that the source is located in the exact center of a large sphere, then the power P of the sound wave is distributed evenly over the surface area A of the sphere. Consider five scenarios where the power of the source depends on some constant P , and the radius of the sphere depends on some constant R . Arrange the intensities of the sound waves from lowest to highest.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
