learn to pronounce

noun

the practice of taking someone else's work or ideas and passing them off as one's own.

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.

b is the correct answer

mark me brainliest and hope this

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
