In a meteorological experiment, a high-altitude research balloon is filled with helium gas. Under the constant temperature and pressure conditions of the stratosphere, 14.2 g of helium gas is found to occupy a volume of 85.2 dm3.
Calculate the mass, in grams, of helium gas that would occupy a volume of 298.2 dm3 under these same stratospheric conditions.
