A sample of sulfur dioxide gas (SO2) is initially at a temp of 133 degrees celcius, a volume of 20 L, and a pressure of 850 mmHg. If the volume changes to 25 L and the temp increases to 181 degrees Celsius, find the new pressure
Physical Chemistry
A gas at STP occupies 28cm^3 of space. If the pressure changes to 3.8 ATM and the temp increases at 203 degrees celcius, did the new volume. (Hint: 1cm^3 = 1 mL)
Physical Chemistry
A sample of gas has an initial volume of 25 L and an initial pressure of 3.5 ATM. If the pressure changes to 1.3 ATM, find the new volume, assuming that the temp remains constant.

Can anyone please tell me why cmc of sdbs (sodium dodecyl benzene sulphonate) decreases in ethanol(either 1% or 2%) but it is more in water???
moreover m calculating cmc through conductivity meter . I'll b really thankful :)

Physical Chemistry
2A(g) + B(g) ⇌ C(g)(exothermic)At equilibrium a 2 L container contains 2.0 mol of A, 0.04 mol of B and 1.2 mol of C gases at a constant temperature. If the temperature inside the container is increased and then some of gas A is removed from the container; the molar concentration of B becomes 0.128 M at the new equilibrium and the equilibrium constant becomes 1/10 times of its initial value. What is the number of moles of gas A removed?
Physical Chemistry
2A(g)+B(g)⇌2C(g)At equilibrium a 6 L container contains 6.0 mol of A, 0.18 mol of B and 3.6 mol of C gases. At a constant temperature the volume of the container is decreased to 4 L and some C gas is added. When the new equilibrium is established, the mole number of B is found to be 0.3. What is the mole number of C gas added into the container???
