From the volume of the flask, and the density of air under the conditions in the room, you can calculate the mass of air. The density of air varies with pressure, temperature, humidity, etc. At sea level and at 15 °C air has a density of approximately 0.001225 g/ml, so under these conditions, a liter flask would contain (1000 ml)(0.001225 g/ml) = 1.225 g of air.
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.
To prepare a 40% solution of potassium sodium tartrate, you would need to weigh out the appropriate amount of the salt and dissolve it in a specific volume of water to get the desired concentration. For example, to prepare 100mL of a 40% solution, you would mix 40g of potassium sodium tartrate with enough water to bring the final volume to 100mL.
The mass of an empty 100ml beaker can vary depending on the material it is made of. For a typical glass beaker, the mass is usually around 100-150 grams. However, for a plastic beaker, the mass may be lighter, around 20-50 grams. It is important to use a balance to measure the exact mass of the specific beaker you are using in a scientific experiment.
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
100mL is not a measurement of weight. mL are a measurement of volume. If you want to compare the weight of something to the weight of 100mL then you need to say what you have 100mL of because 100mL of oil will weigh more than 100mL of water
mL usually doesn't represent weight. But, mL meansmilliliters, so the 500 mL flask would be 500 milliliters.
100ml of water weighs approximately 100 grams. Adding 15 grams of salt would bring the total weight to 115 grams.

Weigh 3g Salt into a 100ml container and bring to volume with deionized water. Mix well. This will be a 3% standard. Other standards are made in the same way (ex.: 2g in 100ml water = 2.00% or 2.5g in 100 ml = 2.50%). I use this in my lab when I make our standard. Hope your not getting this information to late!
