Calculate the average atomic mass of hydrogen using the following data : {:("Isotops",%"Natural abundance","Molar mass"),(.^(1)H,"99.985","1"),(.^(2)H,"0.015","2"):} |
|
Answer» <P> Solution :`"Average atomic mass "= (Sigmap_(i)A_(i))/(100)""(p_(i)="PERCENT abundance, "A_(i)="atomic mass of ISOTOPE ")``=(99.985xx1+0.015xx2)/(100)=(99.985+0.030)/(100)=(100.015)/(100)=1.00015u.` |
