1.42g/cm^2 to mg/mm^2

The value in milligram per square millimeter is

Explanation:

We are given a value of

To convert this value into milligrams per square millimeters, we use the conversion factor:

1 g = 1000 mg

Converting the above speed into miles per hour, we get:

Hence, the value in milligram per square millimeter is

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

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.
