HERE IS YOUR ANSWER :-

______________________________
________________________________

WEIGHT OF ZINC = ( GIVEN NUMBER OF ATOM / NUMBER OF ATOM IN ONE MOLE) * MOLECULAR WEIGHT OF ZINC

WEIGHT OF ZINC = (6.203 * 10^21 /6.023 * 10^23) * 65.4 gram

=> (6.203 * 10^21/6.023* 10^23) * 65.4

=> (1.02/10^2) * 65.4

=> 1.02 * 10^-2 *65.4

=> 66.7 * 10^-2

=>0.667gram
