In a proctor test, 1.8 kg of moist soil was filled in the mould (volume = 944 cc) after compaction. A soil sample weighting 23 g was taken from the mould and oven dried for 24 hours at a temperature of 110°C. The weight of the dry sample was found to be 20 g. The specific gravity of soil solids is G = 2.7. The theoretical maximum value of the dry unit weight of the soil at that water content is equal to _____
