Solution 33E: Here we need to convert first billion ton to ton and then ton to gram (g) We know, We need to convert 1 billion ton to ton 9 1 billion = 10 1 billion ton = 1 x 10 ton9 9 35 billion ton = 35 x 10 ton And Conversion of ton to gram(g) 1.0 ton = 10 g6 35 x 10 ton = (35 x 10 x 10 )g 6 15 = 35 x 10 g Thus, the mass of 35 billion ton CO is equal to 35 x 10 g 15 2 Now we have to convert 35 x 10 g into metric prefix We know 1 peta = 10 15 15 1 petagram =1.0 Pg= 1 x 10 pg The abbreviation of peta is “P” Therefore 15 The mass of 35 billion ton CO is equal2o 35 x 10 g = 35 petagram= 35Pg
