Cuántos gramos de hierro están contenidos en una masa de sulfato férrico, de manera que esta última sustancia contenga 3/5 del número de moléculas que contiene 220 gramos de CO2? P. A. (uma) : Fe = 56 ; S = 32 ; O = 16 ; C = 12

How many grams of iron are contained in a mass of ferric sulfate, so that this last substance contains 3/5 of the number of molecules that 220 grams of CO2 contains? P.A. (amu): Fe = 56; S = 32; O = 16; C = 12

336 g

Explanation:

Given

220 grams of CO2

MW elements : (amu): Fe = 56; S = 32; O = 16; C = 12

Required

mass of Iron

Analysis

find mol of CO₂ and number of molecules

find molecules, mol and mass of ferric sulfate

find mass of Iron

Solution

:

mass of Iron

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
