What is the mass of a gold bar?

27.4

Explanation:

A standard gold bar weighs 12.4 kilograms (which is 400 troy ounces, or 27.4 pounds). Banks across the world use this weight.

I know this is going to be weird but you're going to have to use the mass formula mass equals weight divided by the acceleration of gravity m equals w divided by g converting the rate that is measured into pounds is equivalent to the Newton's and the formula determining the mass based on the height so basically the mass is going to be measured by Newtons

so just for equal breakdown just use m equals w divided by g

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.
