Is it impossible to convert ml into grams because grams is a unit for weight and ml is a unit for volume?
For example; for Glucose i only know the molecular weight which is 180g/mol-1 and the volume of solution in which the glucose is in 20ml. I also know in this 20ml solution there is 2.0% of glucose present.
Can i use this information to calculate the weight in grams of glucose or is that impossible??

Maybe if i ssolve it this way may help:
density= mass/volume
=180 gmol / 20
= 9 g/ml
Mass= volume of glucose in 20ml * density
=0.4ml * 9= 3.6g
worth a shot right? xxxxx

i'll let you figure out the glucose conversion.
I can tell you this, which well help your glucose problem.
g is a unit of mass (not weight) and ml is volume. I know that cm^3 is equal to a mL.
you can't really convert mL to grams directly without density.
we know that 1 g of water is just 1 mL because the density of water is 1g/mL.
but density = mass/volume. So if you know two of those units you have the other.

Milliliters are volume, while grams are mass, Therefore, there's no direct conversion because they're like apples and oranges. However, if you're talking about a certain number of milliliters of a substance with a known density, then it is easily possible to calculate the number of grams of the substance. A milliliter is also a cubic centimeter. In the metric system, densities are usually given in grams per cubic centimeter (g/cm^3). As an example, suppose you were asked to calculate the mass in grams of 15 milliliters (ml) of mercury. Mercury has a density of about 13.53 grams per cubic centimeter, and 15 ml = 15 cubic centimeters. Therefore, the mass of 15 milliliters of mercury = 13.53 g/cm^3 x 15 cm^3 = 202.95 grams.

180g/mol-1 X 20mL X 2/100 X ( ) =?
ok, I'm stuck. Do you have a conversion for mol to mL? You have to put it in the parentheses. Sorry I couldn't finish it for you.

milliliters is volume where grams is mass. but as you have the molar mass you can solve this problem with the information you have. good luck.

mass = volume * density.
mass = gram
volume = millilitre (or cubic centimeters)
