If 3.99 Lof F2 gas is cooled to 32°C where it occupies a volume of 255 L at that cooler
temperature, then what was the original temperature, in Kelvins? Don't forget to use
Kelvins and round to ones place (so you don't have to worry about using scientific
notation).

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
