What does a flask measure?
Volume.
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
A gas originally at 27C and 1.0atm pressure in a 3.9 L flask is cooled at constant pressure until the temperature is 11C What is the new volume of gas?
3.7 L
If A flask contains 440 mol of liquid bromine Determine the number of bromine molecules in the flask?
A flask contains 0.410 of liquid bromine, . Determine the number of bromine molecules present in the flask.
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.
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 a flask measure?
Volume.
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.
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.
What unit of measurement does a Beaker or Erlenmeyer flask use?
Milliliters, sometimes liters
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
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.
Does a flask have a meniscus?
Yes. A meniscus is a visible curve in a liquid caused by the attraction of the liquid for the sides of the flask. Read the volume of your flask from the bottom of the meniscus.
What are ways to measure volume?
Beaker, flask, jug.
Is the volume occupied by the gas in the flask approxmately the same greater or less than before it was heated?
Assuming the flask is sealed - the volume remains the same but the pressure increases
