Resposta:

1) 32g ----- 6.10^23

80g ----- x

x = 80.6.10^23/32

x = 15.10^23

2) 6.10^23 ----- 131

4,02 ------ x

x = 131.4,02/6.10^23

x = 87,77g

3) 90g ---------- x

18g ---------- 6.10^23

x = 90.6.10^23/18

x = 30.10^23

4) 200g ------- x

56g -------- 6.10^23

x = 200.6.10^23/56

x = 21,8.10^23

5) 0,2 ------- x

1 ------ 178

x = 178.0,2

x = 35,6g
