Question

Cuantos moles y atomos de oxigeno hay en 180 g de c6h12o6 !

Answer 1

Mm C6H12O6 = 180 g/mol

1. calcular moles de glucosa

moles = 180 g Glucosa  x   1 mol Glucosa     x  6 mol Oxigeno
                                             ````````````````````      ````````````````````
                                             180 g Glucosa       1 mol Glucosa

mol O2 = 6

2. calcular átomos de Oxigeno

        1 mol ---- 6.022 x 10²³ átomos
        6 mol -----         x

           x = 3.61 x 10²⁴ átomos
