Question

How I calculate mass fraction ratio?

Answer 1

For a chemical compound...

Explanation:

Suppose,a compound is `color(red)(X_aY_b`...

Now you have to determine mass fraction...

Suppose the atomic weight of `X` and `Y` are respectively `m_1` and `m_2`...
We can determine the total mass of the compound `X_aY_b` to be `{(m_1xxa)+(m_2xxb)}` unit.

Now you have to determine the mass fraction of the element `X`:-
The mass of the element `X` in the compound is `(m_1xxa)`
`color(red)(ANS...`
The mass fraction of the element `X` in the compound `X_aY_b` is `(((m_1xxa))/{(m_1xxa)+(m_2xxb)})`

Similarly,for the element `Y` it is `(((m_2xxb))/{(m_1xxa)+(m_2xxb)})`

For complex compounds you can follow the same process...

Hope it helps...
Thank you...
