Question

If a rocket runs on a fuel ( C 15 H 30) and liquid oxygen, the weight of oxygen required and CO 2 released for every litre of fuel respectively are: (Given: density of the fuel is 0.756 g / mL ) (A) 1188 g and 1296 g (B) 2376 g and 2592 g (C) 2592 g and 2376 g (D) 3429 g and 3142 g

C 15 H 30+(45/2) O 2 arrow 15 CO 2+15 H 2 O Mass of fuel =0.756 × 1000 g No. of moles of fuel =(0.756 × 1000/210) Wt. of oxygen =(0.756 × 1000/210) × (45/2) × 32=2592 g Wt of CO 2=(0.756 × 1000/210) × 15 × 44=2376 g

Q. If a rocket runs on a fuel $(C_{15} H_{30})$ and liquid oxygen, the weight of oxygen required and $C O_{2}$ released for every litre of fuel respectively are: (Given: density of the fuel is $0.756 g / m L$ )

$1188 g$ and $1296 g$

$2376 g$ and $2592 g$

$2592 g$ and $2376 g$

$3429 g$ and $3142 g$

Q. If a rocket runs on a fuel (C15​H30​) and liquid oxygen, the weight of oxygen required and CO2​ released for every litre of fuel respectively are: (Given: density of the fuel is 0.756g/mL )
