Three compounds containing potassium and oxygen 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.

Starting with the compound with the least mass of potassium, create a ratio for the rest of the compounds:

$1.00gO=1.22gK$

Then, divide the next greater value of mass of K by the least value for the mass of K

$2.44gK\xf71.22gK=2$

Repeat with the next greater value of mass of K

$4.89gK\xf71.22gK=4.008\approx 4$

The established ratio was that for each 1.22 gK there is 100 g O, thus the quotients acquired are the ratio of oxygen per each mass of potassium presented

a.) For every 1.22 g K there is 1.00 g O;$\frac{1}{1}$

b.) For every 2.44 g K there is 2 of 1.00 g O;$\frac{1}{2}$

c.) For every 4.89 g K there is approximately 4 of 1.00 g of O;$\frac{1}{4}$

Then, divide the next greater value of mass of K by the least value for the mass of K

Repeat with the next greater value of mass of K

The established ratio was that for each 1.22 gK there is 100 g O, thus the quotients acquired are the ratio of oxygen per each mass of potassium presented

a.) For every 1.22 g K there is 1.00 g O;

b.) For every 2.44 g K there is 2 of 1.00 g O;

c.) For every 4.89 g K there is approximately 4 of 1.00 g of O;

The law of proportion states that elements combine in whole number ratios.

The gram readings for K are multiples of each other, both in grams and moles.

Let us compare the ratios:

$\frac{2.44grams}{1.22grams}=2$

$\frac{4.89grams}{2.44grams}=2$

Therefore, Potassium always combines with Oxygen ina ratio of 2 is to 1.

The gram readings for K are multiples of each other, both in grams and moles.
