PLEASE HELP WITH CHEMISTRY HW ASAP!(If possible put the formula used) 1.A gas takes up a volume of 20 ml, has a pressure of 3 atm, and a temperature of 100 C. What is the new volume of the gas at stp?
2.A sample of nitrogen occupies a volume of 200mL at 40 C. What volume will it occupy at STP if P constant
3.The gas in an aerosol can is under a pressure of 4 atm at a temperature of 50 C . It is dangerous to dispose of an aerosol can by incineration. What would the pressure in the aerosol can be at a temperature of 60 C if the volume is held constant?
