A 30 kg object takes one MINUTE to travel east 240 m. It began travelling at 240 m/s and came to a stop (0 m/s) at the end. What was its acceleration? 8

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

will have a gram-molecular weight of 352g.

here are some of the ways in which chemical and nuclear reactions differ.
