$density = \frac{mass}{volume}$

mass of C₁₅H₃₀ = d × V = 0.756 × 1000 = 756 gram

$C_{15} H_{30} (ℓ) + \frac{45}{2} O_{2} (g) \overset{}{\to} 15 {CO}_{2} (g) + 15 H_{2} O$

$\frac{756}{210} \frac{45}{2} [\frac{756}{210}] mole 15 [\frac{756}{210}]$

$W_{O_{2}} = \frac{45}{2} [\frac{756}{210}] 32 = 2592 gram$

$W_{{CO}_{2}} = 2376 gram$
