Abacterial culture isolated from sewage produces 0.376 l of methane (ch4) at 304 k and 1.5 atm. what would the volume of the methane be at stp?
a particular chemical reaction requires 295 mol sulfur dioxide gas (so2) a scientist has a 5.2 l tank of so2 gas at a pressure of 45.2 atm and a temperature of 293 k. does the scientist have enough so2 to carry out the reaction? if so, how many moles of so2 will be left over? if not, how many more moles of so2 does the scientist need? explain your answer.
the maximum safe pressure that a 4.00 l vessel can hold is 3.50 atm. if the vessel contains 0.410 mol of helium, what if the maximum temperature to which the vessel can be subjected?
a 3.4 l rigid container holds a sample of argon (ar) gas at a pressure of 1.0 atm and a temperature of 263 k. if a scientist adds 2.5 mol ar to the container without changing the temperature or volume, what will the new pressure inside the container be? (hint: first calculate the number of moles that were in the container originally)
me, i don't really understand this.
