Let the percentage of X-16 isotope =x The percentage of X-18 isotope =(100-x) From the information the average atoic mass of the element X is = x×16100+(100−x)×18100 But the given atomic mass of the element X=16.2 u x×16100+(100−0x)×18100 16x+1800-18x=16.2×...
The average of a property means the combined mass of the samples to be weighed divided by the number of samples. The average of a property is a value used to represent the whole rather than using the value of one of the samples...
