How can the calculation for the mole fraction of ethylene glycol in water be written? O XEG = neg/(NEG + NH320)
O XEG = neg * (NEG + nH20)
O XEG = neg/nH20
O XEG = neg + NH2O

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
