Percentage composition of a mineral is: ...

Percentage composition of a mineral is: `CaO=48%,P_(2)O_(5)=41.3% and CaCl_(2)10.7%`. Determine the formula of that mineral.

Text Solution

Verified by Experts

Ratio of the numbe rof `CaO,P_(2)O_(5) and CaCl_(2)` molecules present in a moelcule of the mineral is
`CaO:P_(2)O_(5):CaCl_(2)`
`=(48)/(40+16):(41.3)/((2xx31+5xx16)):(10.7)/((40+2xx35.5))`
=8571:0.2908:0.0964=8.9:3.0:1`~~`9:3:1
`therefore` Formula of the mineral: `9CaO*3P_(2)O_(5)*CaCl_(2)`
