Question

1 gram of Co2 is produced by burning 3/11 gram of carbon,the equivalent weight of carbon is?

Answer 1

Mass of carbon = 3/11

Mass of oxygen = 1 - 3/11 = 8/11

Equivalent mass = (mass of carbon/mass of oxygen) x 8

Equivalent mass = [(3/11)/(8/11)] x 8

                            = (3/11 x 11/8) x 8

                            = 3/8 x 8

                            = 3g

Answer 2

Answer:

Explanation:

Mass of carbon = 3/11

Mass of oxygen = 1 - 3/11 = 8/11

Equivalent mass = (mass of carbon/mass of oxygen) x 8

Equivalent mass = [(3/11)/(8/11)] x 8

= (3/11 x 11/8) x 8

= 3/8 x 8

= 3g
