Question

Three compounds containing potassium (K) and oxygen (O) are compared. Analysis shows that for each 1.00 g of O, the compounds have 1.22 g, 2.44 g, and 4.89 g of K, respectively. Show how these data support the law of multiple proportions.

Answer 1

Answer:

1.00 g of O = 1.22 g of K

We were given that for every gram of oxygen there is 1.22 g of potasium.

2

1.22 g x 2 = 2.44 g

and 1.22 g x 4 = 4.89 g

By adding another compound the amount of potassium increases by the same amount in the problem.

RESULT

1.22 g x 2 = 2.44 g

and 1.22 g x 4 = 4.89 g
