Answer 1

128 g S02                                 Se calculeaza MSO2=32+2 .16=64------>1mol=64 g

                                                 Aici se cunoaste cantitatea de sulf =32g

gS                                                Trebuie aflata cantitatea de sulf din 128 g.

                                           Daca in 64 g SO2 se afla 32 g S ,atunci in   128g SO2   

Xg sulf.                                se afla x g S

                                                    64g SO2------------32 g S

                                                      128g SO2----------Xg S

                                                       X=128.32:64=64 g S
