# How I calculate mass fraction ratio?

##### 1 Answer

Oct 9, 2017

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...
