The main thing is, it's more usual to eliminate the superfluous zeros entirely and use the form "10⁻²" rather than "100⁻¹".

I'll admit to being facetiously pedantic in rendering "6gx100g^-3" by including the g units in the exponential calculation, such that g×g⁻³ = g⁻² after having managed to mess up the first calculation (which should read 0.0326, etc.), as well as it slowly dawning on me here () that the "100g^1" format is a slightly unusual way of writing "percent"/"%". Perhaps this is a result of complications arising through their document encoding systems, since percent codes would potentially lead to, for example, whatever character is represented by the digits following the percent sign - but normally a percentage would be followed by a space, a full stop (period) or a comma, and not digits. I can also appreciate that the authors will have had to translate their work into English, presumably from Mandarin, which leaves me wondering if there's a correlation to the way percentages might be written in Chinese.

Apologies for the diversion, hope it's still of some use!
