a sample of neon is collected by displacing 182 ml of water. The pressures of the gas and the atmosphere are equalized, using the method described in the decomposition of potassium chlorate. The atmospheric pressure is 738 mmhg. The temperature of the water and that of the gas are identical at 26oC. how many moles of helium have been evolved
