mL usually doesn't represent weight. But, mL meansmilliliters, so the 500 mL flask would be 500 milliliters.
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
The weight of 100 mL of a substance can vary depending on its density. For water, 100 mL is equal to 100 grams. However, for other substances, you would need to know the density to convert volume to weight.
Oh, dude, the mass of a 50 ml Erlenmeyer flask is gonna depend on the material it's made of. If it's glass, it might weigh around 50-100 grams, but if it's plastic, it could be lighter. Just slap that bad boy on a scale to find out for sure. Like, it's not rocket science, man.
By definition, a 10 molar solution contains 10 moles of the solute per liter of solution. Therefore, since 100 ml is 1/10 of a liter, 100 ml of such a solution would contain one mole of the solute. Physically, this would normally be accomplished by adding 10 grams, stated to be one mole of the solute, to a 100 ml volumetric flask, then adding pure water until the mark on the neck of the flask is reached.
The weight of 100 ml of a substance depends on the substance's density. To convert ml to grams, you need to know the density of the substance in question. Once you have the density, you can use the formula: mass = volume x density.
100g
The weight of 100 ml of a substance will vary depending on its density. However, for water, which has a density of approximately 1 g/ml, 100 ml would weigh approximately 3.5 ounces.
A 1-liter flask will hold 20 50-mL quantities.
As a rule of thumb, your vol. should not be above 2/3 of total capacity of the flask. Do a back calculation for 75 mL EtOH, use ~150 ml capacity and above but try not to use too large boiling flask. I will stay say between 150-250mL.
Need weight or volume, but 1 gm in 100 ml = 1% SOLULION
