一、一种气体遇水后的计算题例1 在标准状态下,充满了干燥氨气的烧瓶,倒置于水槽中,最后若烧瓶完全充满水,则烧瓶内氨水溶液的物质的量浓度最接近的数值是()。A.1×17/22.4mol/L B.1/17mol/LC.1/22.4mol/L D.无法计算解:设烧瓶体积有xL则氨气的物质的量是:x/22.4mol氨水的物质的量浓度=(x÷22.4)mol÷xL=1/22.4mol/L故答案选C。
First, a calculation example of a gas encountered in water 1 In the standard state, filled with a flask of dry ammonia gas, inverted in the sink, and finally if the flask is completely filled with water, the ammonia concentration of the solution in the flask is the closest The value is (). A. 1 x 17/22.4 mol/L B. 1/17mol/LC. 1/22.4mol/L D. Can not calculate the solution: Let the volume of the flask have xL then the amount of ammonia material is: x/22.4mol of ammonia, the amount of material concentration = (x ÷ 22.4) mol ÷xL = 1/22.4mol / L so the answer C.
