Calcualte the number of oxygen atoms in 88g CO_(2). What would be the mass of CO having the same number of oxygen atoms? |
|
Answer» Solution :88g `CO_(2)=2` moles of `CO_(2)`One molecule CONSISTS of 2 OXYGEN atoms. No. of oxygen atoms `=2xx2xx6.02xx10^(23)=24.08xx10^(23)` CO molecuel has one oxygen atom. Mass of CO containing 24.08`XX 10^(23)` oxygen atoms `=(28)/(6.02xx10^(23))xx24.08xx10^(23)=112g` |
