Answer 1

Răspuns:

Explicație:

2 Cs ------> 2.133=266----> 266g/moli de atomi

5 Fe------> 5.56 = 280 -----> 280g/moli  de atomi

7 C------> 7 .12 = 84 ----> 84g/moli de atomi

3 Mn ------> 3.55 = 165------> 165g/moli de atomi

4Pt --------> 4 . 195 =780------> 780g/moli de atomi

6 Kr ------->6.83 = 503 ------> 503 g/moli de atomi

8 Ar --------> 8.40 =320 ------> 320 g/moli de atomi

10 Pb ------> 10.207= 2070 ------> 2070g/moli de atomi
