Answer 1

SO2

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

x..................y................100g SO2

y=32*100/64=50% O

x = 100-50=50% S

Ca(NO3)2

40g Ca......28g N.........96g O......164g Ca(NO3)2

x............y.................z.............100g Ca(NO3)2

x=40*100/164=24,39% Ca

y=28*100/164=17,07% N

z = 100 - 24,39 - 17,07 = 58,54% O
