What does a flask measure?
A flask typically measures volume or capacity in units such as milliliters (mL) or liters (L). It is commonly used in scientific laboratories to accurately mix, store, or transfer liquids.
After 0.600 L of Ar at 1.20 ATM and 227 degrees celsius is mixed with 0.200 L of 0xygen gas at 501 torr and 127 celsius in a 400 ml flask at 27 celsius what is the pressure in the flask?
Total P ( in the flask) = Partial pressure(Ar) + Partial pressure (O2) = [ n(Ar) +n(O2) ]*RT(final) / V(inal) = [(1.2 * 0.6 / 0.0821*500)+( 501/760)*0.2/0.0821*400)] *0.082 * 300 / 400/1000 = 1.33 atm
If A flask contains 440 mol of liquid bromine Determine the number of bromine molecules in the flask?
There are approximately 2.65 × 10^26 bromine molecules in the flask. This is calculated by multiplying Avogadro's number (6.022 × 10^23 molecules/mol) by the number of moles of bromine present in the flask (440 mol).
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.
What is the use of iodine flask?
An Iodine Flask is essential an Erlenmeyer Flask with a stopper used for the wet chemical analysis "Iodine Determination" . This analysis is typically performed on fatty acids, oils and shellac varnishes.
What does Tc 20 degrees celsius stand for?
To contain at 20 degrees celsius. To contain at 20 degrees Celsius. This would be written on a graduated cylinder or a volumetric flask.
Assume you seal 1.0 g of diethyl ether in an evacuated 100 mL flask If the flask is held at 30 degrees Celsius what is the approx gas pressure in the flask?
At 30 degrees C, the vapor pressure of ethe is about 590 mm Hg. (The pressure requires 0.23 g of ether in the vapor phase at the fiven conditions, so there is sufficient ether in the flask.) At 0 degrees C, the vapo pressure is about 160 mm Hg, so some ether condenses when the tempeature declines.
Gas is contained in a 125mL flask The actual volume of the flask is 131.5mL What is the volume of the flask in L?
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
What does the Erlenmeyer flask measure?
A graduated Erlenmeyer flask can measure a volume.
What is the volume capacity of a flask?
The answer depends on the flask: they are not all the same size.
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 calibrate a volumetric flask?
To calibrate a volumetric flask, you need to fill it with a known volume of liquid, usually water, at a specific temperature. Then, you measure the actual volume of liquid in the flask using a calibrated measuring device, such as a graduated cylinder or a pipette. The difference between the known volume and the measured volume is the calibration error, which can be used to adjust the accuracy of the flask.
What is the least count of a flask?
The least count of a flask refers to the smallest volume that can be accurately measured with that specific flask. It is determined by the accuracy of the markings on the flask and is typically specified by the manufacturer.
Sam filled a 500ml conical flask with 200ml of water Then he attached a 100ml syringe full of air to the conical flask and pushed the plunger inwards What was the volume of air in the flask?
The total volume in the flask is 500ml of water + 100ml of air from the syringe, which equals 600ml. Since the 200ml of water takes up space in the conical flask, the remaining volume for air is 400ml.
What becomes when 300ml in a container 'n' 1000ml in a flask?
The total volume in the container and the flask is 1300 ml.
What is the volume of a round flask with diameter of 12 millimeters?
Not enough information has been given such as the height of the flask.
What are ways to measure volume?
Beaker, flask, jug.
