5. A student has a 5.00 gram sample of calcium chloride (CaCl) solid. How many moles of calcium chloride are contained in this sample?

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

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
