What is the density of octane at STP?

Question

What is the density of octane at STP?

Answer 1

The density of octane is 0.703 g/ml, liquid.

But for more information about octane, you can go to http://en.wikipedia.org/wiki/Octane

Answer 2

Relative Molecular Mass Of C8H18 (C = 12,H = 1)

Molar Mass = 8(12)+18(1) = 114 g mol-1

Molar Volume Of Gases at STP (22.4dm3 mol-1)

Density of Octane at STP ;

114 g mol-1/22.4dm3 mol-1 = 5.09 g/dm3 (5.09 g/litre)

Density of Octane (Liquid) is 698.6 kg/m3.
