Paper weighing 75 g/m² and 0.1 mm thick (I am making up the numbers, not sure about paper thickness)
75 g/m² / 0.1 mm = 750 kg/m³...

Gsm = g/m². Divide by the thickness (expressed in meters) to get grams per cubic meter. It would be customary to then divide by 1000 to get kg/m³, the...Leave a comment:

Yes, that is correct. The MW is immaterial as you are not converting moles to grams....Leave a comment:

You are not changing units, only prefixes.
500 fmol/mL x 1 pmol/1000 fmol x 1000 mL/L = 500 pmol/L
(both l and L are assigned symbols...Leave a comment:

Ppm is ambiguous and meaningless unless you define the basis of the ratio. Gases are usually expressed as a molar ratio; for ideal gases (or nearly ideal)...Leave a comment:

I am not 100% sure of this, but I think it will help
You took only 20 µL of the 1000 µL hydrolysate, so only 15 mg x 20µL/1000 µL of the original...Leave a comment:

I believe we are missing two critical pieces of data:
1) "I hydrolyzed 15mg of sample" On what volume of water (or solvent)? We need the...Leave a comment:

Convert all dimensions to meters, then multiply. I'll do one, follow the example for the other. 2nd size
0.91 m x 1.82 m x 0.009 m = 0.0149058 m³...Leave a comment:

At least in the version I downloaded, SI conversion factors are given immediately under the table. Simply multiply the Customary values by these conversions....Leave a comment:

Moles of what? You need to divide by the molar mass, which is specific to the substance and adjust prefixes.Leave a comment:

Concentration or amount?
M is the symbol for molarity, a concentration in moles per liter (mol/L). A 1 M solution is one mole (or one molar mass)...Leave a comment:

I assume the units of the given density are g/cm3, so 680 kg/m3, and the areal density 0.122 kg/m2
0.122 kg/m2 x 1 m3/680 kg = 0.000 1794 m or 179.4...Leave a comment:

You have to know the density of the material in kg/m³. Gsm is g/m². Divide by 1000 to get kg/m², then divide by the density in kg/m³ to get thickness...Leave a comment:
