If you know the density and the mass of an object, what formula would you use to calculate its volume?

The set equation relating mass, density, and volume is D=m/v or density equals mass divided by volume. 2 Plug your values into the equation. If the density of your object is 500 kg/m 3 (kilograms per cubic meter), then you put 500 in place of the D for 500=m/v.

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.
