Which of the following accurately describes circuits? Question 20 options: A) In a parallel circuit, there's only one path for the current to travel. B) In a series circuit, the current can flow through only one path from start to finish. C) In a series circuit, the amount of current passing through each part of the circuit may vary. D) In a parallel circuit, the same amount of current flows through each part of the circuit.

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.
