1) \(m_{Fe}=n_{Fe}.M_{Fe}=0,05.56=2,8\left(g\right)\)
2) \(m_{H_2}=n_{H_2}.M_{H_2}=1,5.2=3\left(g\right)\)
3) \(m_{N_2}=n_{N_2}.M_{N_2}=0,03.\left(14.2\right)=0,84\left(g\right)\)
4) \(m_{Al}=n_{Al}.M_{Al}=0,2.27=5,4\left(g\right)\)
5) \(m_{Al_2\left(SO_4\right)_3}=n_{Al_2\left(SO_4\right)_3}.M_{Al_2\left(SO_4\right)_3}=0,5.\left[27.2+\left(32+16.4\right).3\right]=171\left(g\right)\)
6) \(m_{Cu\left(OH\right)_2}=n_{Cu\left(OH\right)_2}.M_{Cu\left(OH\right)_2}=0,2.\left[64+\left(16+1\right).2\right]=19,6\left(g\right)\)
