Agreat natural and humanitarian disaster occurred when the volcano mt pelee erupted on the island of martinique in 1902. an effect of the eruption was a phenomenon called a "nuee ardente" in which a large cloud of hot gas is emitted and rolls down the mountainside, in this case enveloping the town of saint pierre and killing 30,000 people. since the ambient temperature was around 20 c, it's clear that the high-temperature cloud must have been composed of a high-molecular mass gas in order for it to sink rather than rise. suppose the temperature in the cloud was 600 c. estimate the minimum value, in atomic mass units (amu), of the average molecular mass of the gas in the cloud. (assume the ambient air is primarily nitrogen, 28 amu.) amu
