Molar mass of C = 12.01 g/mol
mass of C = 4 g
mol of C = (mass)/(molar mass)
= 4/12.01
= 0.3331 mol
Balanced chemical equation is:
1C ---> 2SO2
According to balanced equation
mol of SO2 formed = (2/1)* moles of C
= (2/1)*0.3331
= 0.6661 mol
Molar mass of SO2,
MM = 1*MM(S) + 2*MM(O)
= 1*32.07 + 2*16.0
= 64.07 g/mol
mass of SO2 = number of mol * molar mass
= 0.6661*64.07
= 42.68 g
Answer: 43 g
