19.25g of C4H10

Explanation:

2C4H10

2×12×4+2×1×10

=116g

8CO2

=8×12+8×16×2

=352 g

116g of C4H10 produces 352 g of CO2

So, x g of C4H10 produces 58.4g of CO2

(cross multiply)

352 x=116×58.4

x=116×58.4÷352

x=19.25g of C4H10

19.25g of C4H10

2C4H10

2×12×4+2×1×10

=116g

8CO2

=8×12+8×16×2

=352 g

116g of C4H10 produces 352 g of CO2

So, t g of C4H10 produces 58.4g of CO2

(cross multiply)

352 t=116×58.4

t=116×58.4÷352

t=19.25g of C4H10
