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.

To calculate the mass of the air in an empty flask, you would first weigh the empty flask. Then, you would fill the flask with air and weigh it again. The difference in weight between the two measurements would give you the mass of the air in the flask.

∙ 7y agoFind the mass of:
- A: the flask with air in it;
- B: the flask filled with water;
- C: the mass of only that water.
Then C - B = mass of flask and A - B = mass of air in the flask.

A 0.200M solution of sodium carbonate Na2CO3 is made by dissolving 5.30g of the solid in water and making up the mark in a standard flask What volume must the flask be?
To find the volume of the flask, first calculate the moles of Na2CO3 using its molar mass. Then use the molarity and moles to find the volume using the formula Molarity (M) = moles/volume (in liters). The volume of the flask needed is then the inverse of the molarity.
How do you prepare 250ml 15m solution of naco3 in a volumetric flask do presume a solvent ie h20 but then you have to presume volumes and conc and because 15M wanted you cant use the flask to dilute?
To prepare a 250ml 15M NaCO3 solution in a volumetric flask without using the flask to dilute, you would first calculate the mass of NaCO3 needed based on its molar mass. Then, dissolve this mass in a small volume of water in a separate container and transfer it quantitatively to the 250ml volumetric flask, and then add enough water to make up to the mark. Finally, mix thoroughly to ensure homogeneous distribution.
What is the mass of an empty steel can?
The mass of an empty steel can is typically around 15 to 20 grams.
What would you need to do to calculate the molality of 0.2kg of nacl in 3kg of water?
To calculate the molality of a solution, you need to know the moles of solute and the mass of the solvent in kilograms. First, calculate the moles of NaCl in 0.2 kg: moles = mass (g) / molar mass. Then, calculate the molality by dividing the moles of solute by the mass of solvent in kg: molality = moles of solute / mass of solvent in kg.
How do you calculate the percentage of mass lost for bicarbonates?
To calculate the percentage of mass lost for bicarbonates, you would first determine the initial mass of the bicarbonate compound. Then, subtract the final mass after the reaction or process from the initial mass to find the mass lost. Finally, divide the mass lost by the initial mass and multiply by 100 to get the percentage of mass lost.
When measuring the mass of NaCl why would you measure the vial and contents then the empty vial?
So that you can calculate the mass of the contents alone, by subtracting the mass of the empty vial from the mass of the vial and contents.
How many 64oz bottles would equal 12grams?
In order to calculate an answer to the question . . . -- We need to know whether or not the bottles are empty. then -- If the bottles are empty, then we need to know the mass of each empty bottle. -- If the bottles have anything in them, then we need to know what it is.
How do you measure the mass of an empty graduated cylinder?
To measure the mass of an empty graduated cylinder, simply use a scale or balance designed for measuring small weights. Place the graduated cylinder on the scale and record the mass displayed. Subsequently, subtract the known mass of the empty graduated cylinder to determine the mass of the cylinder alone.
How do you calculate density of cyclohexen?
cyclohexane is a liquid so it may be filled in a flask of known volume and may be weighted out ... the ratio of mass and volume represents the density....
How do you calculate volume if only mass was given?
You would need to know the density of the object in order to calculate the volume from the mass. The formula to calculate volume from mass and density is: Volume = Mass / Density.
How would an inverted can empty on the moon?
Neglecting the effects of air resistance, it would empty just like on earth only it would be slower. The time it takes would be proportional to the ratio of the mass of the moon to the mass of the earth.
How do you calculate the weight of an empty pressure vessel?
To calculate the weight of an empty pressure vessel, you can determine the volume of the vessel and then multiply it by the density of the material from which the vessel is made. This will give you the mass of the vessel, which you can then convert to weight by multiplying it by the acceleration due to gravity.
How do you calculate mass of a ball?
To calculate the mass of a ball, you would typically use the density of the material the ball is made of and its volume. The formula to calculate mass is mass = density x volume. You would need to know the density of the material and measure the volume of the ball to determine its mass.
How to calculate mass with volume and molarity?
Not enough information. To calculate mass, you would need volume and density (mass = volume x density).
Can an Erlenmeyer flask measure in grams?
No. An erlenmyer flask measures volume, usually in mililiters, but sometimes in liters. Grams is a measurement of mass, and to measure mass you need a ballance.
How can you demonstrate ther is space between molecules of water?
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
Why was it important to determine the mass of the air in the flask?
to make happy
