Use volume for room temperature of 20 degrees Celcius and standard pressure 10^5 Pascals so V = 22.7 * 8.314 * 293 / 10^5 and so 1.81 kg / m^3.

CharcoalA quarter of a bag250grams242500001.0795.70.59.818.5379.70See Johnson (doi:10.1016/j.eiar.2009.02.004 ) table 13 (experimental details table 10&11) Grilling load (amount of food)=1.5kg; Charcoal consumption = 733g; Firelighter consumption = 115g. Therefore 6.7 Kg CO2e/session => 9.7 kgCO2e/kg charcoal use (considering emissions of 115g firelighter) for 1.5 kg of food. Also see 0.8 based on Schmidt Rivera et al 2018 https://doi.org/10.1016/j.jclepro.2018.06.033 says charcoal causes 24 g CO2e / MJ (Fig 14 - actually it says 24 kg CO2e / MJ but based on the other figures I think this is a typo and it should be g CO2e / MJ?) and 34.1 MJ/kg (Table 7) so 24/1000 * 34.1 kg CO2e / kg = 0.81. (See also `` we estimate that 0.77–1.63 kg C‐CO2 (carbon as carbon dioxide equivalents) is emitted per kilogram of charcoal produced.'' from https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2000JD000041).Not known - assumed zero1kg3015582
