In the problem below, which goes into the equation as " n1" ? A gas at 25.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm and 15.0 °C ?

• 15.0 °C but it needs to be converted to Kelvin(K)

• 25.0 °C

• 2.50 atm

• the number of moles of gas are not mentioned in this problem

• this is a graph representing Boyle's law
• this is a graph representing Charles's law
