Dalton is refered toas the father of modern atomic theory why?

John Dalton now and then was referred to as the daddy of contemporary atomic theory. In 1803, he speculated that every one atoms of a given element are identical in size and mass. Dalton; chemist reasoned that elements were composed of smaller atoms. This result in the atomic theory of matter.

John Dalton was known as the father of modern atomic theory, because he stated that all atoms of a given element are identical in size and mass. John Dalton reasoned that elements were composed of smaller atoms. This lead to the atomic theory of matter.

Explanation:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
