【一】‘the lower... the faster...’ 是指‘...越低，...就越快’。【二】 the molecular mass of gas 意思是气体分子量；it will diffuse 是指它将扩散。【总结】气体分子量越低（就是越少），它扩散的速度就越快。希望对你有帮助哦。。。```*/\*```...
MOLAR MASS就是23.0gmol^-1... 1 MOLE的OXYGEN GAS的质量则用RELATIVE MOLECULAR MASS来表达 因为OXYGEN GAS是SIMPLE MOLECULAR STRUCTURE OXYGEN GAS的MOLECULE就是由两粒OXYGEN ATOM组成 所以OXYGEN GAS的RELATIVE MOLECULAR MASS就是16.0X2 即是32.0... 1 MOLE的SODIUM CHLORIDE的质量就用FORMULAR M...
To solve the problem, we need to find the ratio of the partial pressures of gases A and B given the relationships between their densities and molecular masses.1. Understanding the Ideal Gas Law: The ideal gas law is given b
To answer this, we need to be able to estimate the H2 mass.\nTraditionally, this is done using CO and a few assumptions but the Herschel\nobservations in the FIR make it possible to estimate the molecular gas mass\nindependently of CO. Previous attempts to derive gas masses from dust ...
Molecular mass of carbon dioxide (CO2) = ( Atomic mass of carbon C) + ( Atomic mass of Oxygen) x 2 = ( 12 x 1 ) + (16 x 2) = 44g/mole The molecular mass of carbon dioxide CO2 is 44 g/mole. Suggest Corrections 145 Similar questions Q. Calculate the molecular mass of the fo...

Such a direct nonadiabatic (DNA) approach, see Section 2.3, accounts strictly for the (nonadiabatic) effects of the finite mass of the nuclei and has been intensively developed in recent years. Such calculations are relatively costly considering a large number of rovibrational states of the ...

In order to shed light on the ionization process, it is useful to detect the ions in a mass spectrometer, which allows one to determine the mass of the ions. The scheme of the setup for mass-selective ion detection is shown in Fig. 10. The tunable laser light or the frequency-doubled...
