The valve between a 5.00 L tank containing oxygen gas at 9.00 atm and a 7.00 L tank containing neon gas at 6.00 atm is opened. Calculate the final
pressure in the tanks assuming constant temperature.

5.80 atm
7.50 atm
7.75 atm
7.25 atm
None of the above

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
