a)
N(Zn) = m(Zn) / M(Zn) * N(A) = 65 /65 * 6.02*10^23 = 6.02*10^23 at
N(N2) = n(N2) * N(A)*2= 2*6.02*10^23 * 2= 24.08*10^23 at
N(Zn) < N(N2)
b)
N(Cu) = n(Cu)*N(A) = 2*6.02*10^23 = 12.04*10^23 at
N(K) = n(K)*N(A) = 2*6.02*10^23 = 12.04*10^23 at
N(Cu) = N(K)
c)
N(Na) = m(Na) / M(Na) * N(A) = 1/23 * 6.02*10^23 = 0.26*10^23 at
N(K) = m(K) / M(K) * N(A) = 1/ 39 * 6.02*10^23 = 0.15 *10^23 at
N(Na) > N(K)
