Derive the molecular formula of a substance in which the mass fractions of elements are equal, respectively: Hydrogen-2.56%, Silicon-35.9%, Oxygen-61.54%
to find the molecular formula of a substance in which the mass fractions of elements are equal, respectively: Hydrogen-2.56%, Silicon-35.9%, Oxygen-61.54%, you need to make a proportion
61.54% 2.56% 35.9%
O (x) H (y) Si (z)
16 1 28
x: y: z = 61.54 / 16 refers like (:) 2.56 / 1 and refers like (:) 35.9 / 28 = 3.8: 2.6: 1.2 = 4: 3 :one
