a certain substance has a molar enthalpy of vaporization of 31.6 kj mol. How much of the substance is in a sample that requires 57.0kJ to vaporize?
In a beaker, I mix 50 ml of 3 M HCl with 100 ml distilled water. Both fluids are at 25 C initially. (Cp mix =. 0.985 cal/g-C) a. what is the final T.
ideal gas in 2.0 L what will be the volume of the gas if the pressure on the container is doubled while the temperature is reduced from 400 K to 200 K.
How much of methane gas will be produced in anaerobic decomposition assuming a complete conversion of MSW into CH4CO2NO, and SO2.
You have a gas occupying 75L at 800 torr and 315K. What is the volume if the pressure is decreased to 600 torr and the temp is changed to 127 C?
First determine the number of moles of rm Na^+ using the given molarity and volume. Next, use the chemical formula to determine the number of moles of rm Na_3PO_4 needed. Finally, convert moles to grams using the molecular weight of the compound.
The normal respiratory rate for a human being is 15.0 breaths per minute. The average volume of air for each breath is 505 cm3 at 20 ? C and 9.95 × 10 4 Pa.
