What is the gas pressure (in atm) inside a 1.69-L bulb that contains 0.9-g of Ne at a temperature of 34.1 C? Be sure to report the units as atm.
PV=nRT
Is this not the correct setup?
P=[(0.9/20.18)*0.0821*(273+34.1)]/1.69
what is the concentration of toluene in air produced by vaporizing 1 ml of liquid toluene into clean air to produce a total volume of 100 liters? Toluene has a molecular weight of 92
After treatment with trypsin, which cleaves at R and K, there were 3 fragments: two dipeptides and MGAV. What is the sequence of the peptide? Use the one-letter abbreviations for the amino acids, and do not use dashes.
what will the maximum temperature reached by the resulting solution? [Assume that there is no heat loss to the container, that the specific heat of the final solution is 4.18 J/g*C, and the density of the final solution is that of water.]
Calculate the molar solubility of FeCO3 . How many grams of FeCO3 are present in 15.0 L of a saturated solution.
You are given a worked wooden item from an archaeological dig believed to date to during the last glaciation. As such, the artifact would be another piece of evidence.
How many moles of oxygen are needed to react with 5.0 moles of ammonia? In the above reaction, how many moles of water can be produced from 256 grams of oxygen?
A. A student places 2.10 L of water in his dormitory room, which has the volume of 4.06 x10^4 L. He seals the room and waits for the water to evaporate. At 25 deg C, the density of water is 0.997 g/mL
If an analytical method has been developed and the retention time for a particular anabolic steroid has been determined, how might you use this method to determine the possibility of the use of anabolic steroids by an athlete.
Cadaverine, a fould smelling substance produced by the action of bacteria on meat, contains 58.55% C, 13.81% H and 27.40% N. Its molar mass is 102.2 g/mol.
