Question

in a compound carbon nd oxy gen react in ration 3:8 by mass to form carbondioxide. what mass of oxygen is required to react completely with 9g of carbon? answer fast​

Answer 1

hey mate here is your answer

Carbon and oxygen reacts in a ratio 3:8 by mass to form Carbon dioxide

Hence the required reaction is ;

C + O2 --> CO2

Carbon : Oxygen = 3 : 8

Due to law of constant proportion, the mass ratio in which the reactants will react will remain constant.

Carbon --> 9 g

Oxygen --> ?

C : O2 = 3:8

9 : O2 = 3:8

9/O2 = 3/8

Mass of oxygen required

= (9/3)×8

= 3×8

= 24 g
