Nitrogen also has a direct toxic action of its own, affecting brain functions and inducing a stupor or euphoria. That is where molar mass, also called molecular weight, comes in. The nitrogen rule states that organic compounds containing exclusively hydrogen, carbon, nitrogen, oxygen, silicon, phosphorus, sulfur, and the halogens either have 1) an odd nominal mass that indicates an odd number of nitrogen atoms are present or 2) an even nominal mass that indicates an even number of nitrogen atoms in the molecular formula of the molecular ion.

Information system on hazardous substances (GESTIS); German Social Accident Insurance (DGUV); Glinkastraße 40. How many grams of water (H_2O) have the same number of oxygen atoms as 1.0 (mol} of oxygen gas? The molecular weight (or molar mass) of a substance is the mass of one mole of the substance, and can be calculated by summarizing the molar masses of all the atoms in the molecule.. Nitrogen narcosis ("rapture of the deep" or "the martini effect") results from a direct toxic effect of high nitrogen pressure on nerve conduction and produces effects similar to alcohol intoxication. it took 63s for te gas to effuse. You start by writing the formula for nitrogen gas (N2), then you find the molar mass number (it’s on the periodic table usually under the symbol for the element).
