Question

calculeaza compozitia procentuala a dioxidului de sulf2 repedeeee​

Answer 1

calculezi masa molara a SO2

M=32*1+16*2=64 g/mol

32 g S

16*2 g O2

folosesti regula de 3 simpla

64g SO2..........32 g S...........32 g O2

100g SO2........p1%..................p2%

p1%=(32*100)/64=50% g S

p2%=(32*100)64=50% g O2
