关于气体定律,在高一化学教材《摩尔》一章中提出气体摩尔体积和阿佛加德罗定律,然后在该书第五章的一个习题中,作为提示,提出了气体方程的简单形式(P_1V_1/T_1)=(P_2V_2/T_2);此后在实验教材“CCl_4分子量的测定”中,提出了PV=nRT,然而对其运用仅涉及分子量的计算,课文中一直未提及用相对密度法计算气态物质的分子量。我们应结合物理教学和化学作业,以理想气体状态方程PV=nRT为核心,系统地进行气体定律应用于化学计算
With regard to the gas law, the gas molar volume and Avocaro’s Law are proposed in the chemistry textbook “Moore”, and then in the exercises in Chapter 5 of the book, as a reminder, a simple form of the gas equation is proposed ( (P_1V_1/T_1)=(P_2V_2/T_2); Hereafter, PV=nRT was proposed in the experiment textbook “Measurement of Molecular Weight of CCl_4”. However, the calculation of the molecular weight was applied to this, and the relative density method was not mentioned in the text. The molecular weight of the gaseous material. We should combine physics teaching and chemistry operations with the ideal gas state equation PV=nRT as the core, and systematically apply gas laws to chemical calculations.
