What mass of potassium chlorate would contain 40 grams of oxygene

Answer : The mass of potassium chlorate is, 102.125 grams

Explanation:

Potassium chlorate is a compound that contains potassium, chlorine and oxygen atom. The molecular formula potassium chlorate is,

From the molecular formula potassium chlorate we conclude that, there are 1 atom of potassium, 1 atom of chlorine and 3 atoms of oxygen.

The mass of 3 oxygen atom = 3 × 16 = 48 g

The molar mass of potassium chlorate = 122.55 g/mole

As, 48 gram of oxygen present in 122.55 grams of potassium chlorate

So, 40 gram of oxygen present in grams of potassium chlorate

Therefore, the mass of potassium chlorate is, 102.125 grams

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
