Please help and show work 1. Calculate the number of moles of oxygen in a 12.5 L tank if the pressure is 2530 kPa and the temperature is 22 degrees C.
2. Calculate the pressure of 0.30 moles of nitrogen dioxide in a 2.7 L container if the temperature is 27 degrees C.
3. A 35 L tank contains 7.0 mol of compressed air at 500 KPa pressure, what is the temperature in Kelvin and Celsius?
4. Calculate the volume that 2.25 mol of air occupies at STP

the answer is b & c i believe : )

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
