Question

Chlorine reacts with oxygen to form two compounds. Compound A contains 8.43 g of chlorine for every 13.67 g of oxygen. Compound B contains 5.87 g of chlorine for every 17.33 g of oxygen. What is the mass ratio of chlorine rounded to the nearest whole number

Answer 1

The mass ratio for chlorine is = 2 : 1

Step-by-step explanation:

Given that Compound A contains 8.43 g of chlorine for every 13.67 g of oxygen.

`Compound \ A = (8.43 \ gm \ cl_(2) )/(13.67 \ gm \ o_(2) )`

`Compound \ A = (0.6167 \ gm \ cl_(2) )/(1 \ gm \ o_(2) )` -------- (1)

Similarly

`Compound \ B = (5.87 \ gm \ cl_(2) )/(17.33 \ gm \ o_(2) )` --------- (2)

`Compound \ B = (0.338 \ gm \ cl_(2) )/(1 \ gm \ o_(2) )`

`Mass \ Ratio = (Compound \ A)/(Compound \ B)` ------ (3)

Put the values from equation (1) & (2) in equation (3) we get

`Mass Ratio \ M = (0.6167)/(0.338)`

Mass Ratio = 2 : 1

Therefore the mass ratio for chlorine is = 2 : 1
