I hope thats not 1020, but  10^{20}
So, 1.66 x  10^{20} atoms weigh 16.26 milligram
1 atom will weigh  \frac{16.26}{1.66* 10^{20} } milligram
So, 6.022 x  10^{23} atoms weigh  \frac{16.26}{1.66* 10^{20} } * 6.022 x  10^{23}
So, the weight will be 58.986 * 1000 milligrams = 58.986 grams.
Hence the atomic weight of the atom of the Element x is around 59 grams.
1 5 1
yes actually it is 10's power 20
good
actully i m confuse with the answer
