How do you determine the molar mass of an element

At the bottom of the element's box their is a mass number. That is equal to molar mass.

Explanation:

Look at periodic table.

- Hope that helped! Please let me know if you need further explanation.

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.

i'm pretty sure it is letter c.) car
