Un niño recién nacido esta con fiebre. el medico al averiguar la temperatura usa un termómetro calibrado en F y observa que marca 102 ¿Qué temperatura tiene en la escala centígrada CURSO:QUIMICA

TEMA: LA MATERIA

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.

c. is the answer
