2. The element copper has naturally occurring isotopes with mass numbers of 63 and 65.
The relative abundance and atomic masses are:
69.2% for mass of 62.93u
30.8% fora mass of 64.93u.
Calculate the average atomic mass of
copper. .

c u c l 2 + 2 n a n o 3 → c u ( n o 3 ) 2 + 2 n a c l

  long weird answer but i hope this works

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
