Suppose you are a chemical engineer working with a client who produces toothpaste. The client wants to add a blue stripe with mint flavor to the toothpaste. What questions would you ask to begin to address the design problem?

Explanation:

I would ask him why would he want to add the blue stripe?

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.
