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.
What else can I help you with?
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?
Did you mean 250 mL of 0.15 M Na2CO3? (It's impossible to make a 15 M Na2CO3 solution, as Na2CO3 is not that soluble.) Yes, you can assume that this will be an aqueous solution. Steps. 1. Calculate the mass of solid Na2CO3 needed. 2. Place this mass of Na2CO3 in the volumetric flask. 3. Add some water and swirl to dissolve the Na2CO3. 4. Carefully add more water until the total volume of solution is 250 mL, as indicated by the line etched on the neck of the volumetric flask. 250 mL x 1 L x 0.15 mol Na2CO3 x 105.99 g Na2CO3 = 4.0 g Na2CO3 needed ........... 1000 mL ......... 1 L ..................1 mol Na2CO3
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.
What if three identical flasks contain three different gases at stp flask a contains ch4 flask b contains CO2 flask c contains n2 which flask contains the largest number of molecules?
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
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.
What would happen to the mass of the flask and its contents if the balloon was removed?
If the balloon was removed from the flask, the mass of the flask and its contents would remain the same because the air inside the balloon is still part of the system. Removing the balloon does not change the total mass of the system.
What would you observe about the mass in the flask if you did not put the balloon on top?
If the balloon is not placed on top of the flask, the mass inside the flask would remain constant. The balloon is used to capture any gases produced during a chemical reaction, which would otherwise escape into the environment. Without the balloon, the mass of the gases released would not be accounted for, leading to inaccurate measurements of the total mass change in the system.
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?
The easiest way is to place the graduated cylinder on a scale or balance and measure the weight. You would then calculate from the weight (a force measured in kg, usually) to determine the mass.
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 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.
The density of a substance in a sealed 2500 cm3 flask the is full to capacity with 0.36 of a substance?
Density is mass per unit volume. So this gas has a density of: 0.36 / 2500 = 0.000144 mass units per cm3 or 0.0144 mass units per liter or 14.4 mass units per cubic meter (as you have not define the units of mass I cannot be more specific)
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 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 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 to calculate mass with volume and molarity?
Not enough information. To calculate mass, you would need volume and density (mass = volume x density).
