Hello,<\/div>\n
<\/div>\n
I was working on atmospheric composition and asked google methane pubchem molecular weight<\/em><\/span><\/div>\n
<\/div>\n
It came up with 20.067 which traces to<\/div>\n
<\/div>\n
https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/2H4_Methane<\/a><\/div>\n
<\/div>\n
Now I am tired, but carbon is 12.011 and hydrogen is 1.008*4, so the total should be closer to 16.011<\/div>\n
<\/div>\n
Is this page supposed to be deuterated?\u00a0 12.011 + 2*4.0282035557 = 20.067407<\/div>\n
<\/div>\n
But Google got it wrong.\u00a0 Is there some way to label (2H4)Methane as containing 4 deuteriums?<\/div>\n
<\/div>\n
I suggest calling it CD4, or deuterated methane, or at least C(2H)4, or you have to talk to Google.<\/div>\n
<\/div>\n
Not my job to correct Google’s mistakes, but I think your page is very misleading.\u00a0 I could not immediately understand your page without counting on my fingers and toes to figure out why CH4 was used and not CD4<\/div>\n
<\/div>\n
I got the “right” answer by asking average molecular weight of methane site:gov<\/span><\/em><\/div>\n
<\/div>\n
Which leads to https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/Methane<\/a> where the Molecular formula is also CH4<\/div>\n
<\/div>\n
“molecular weight of methane” has 1.08 Million<\/strong> entry points on the Internet and those page ownere are NOT all working together seamlessly for the benefit of the 4.8 Billion Internet users.<\/div>\n
