How many moles of O2 are there if the number of atoms is [x] x 1023 molecules? Round answer to 2 decimal places.

The four thermal layers of the atmosphere in order beginning at the surface and going upward are:

Your surface temperature is 20 degrees C.  Your friend in a hot air balloon up at 1 km informs you that the air temperature up there is 13 degrees C.  Since 20-13=7, you know that the atmosphere’s ELR is 7 c/km (which happens to fall between between the DALR and the SALR rates of 10c/km and 5c/km).  Since the ELR falls between the DALR and SALR, you are able to make the following determination about the layer’s stability:
