Problem

An unknown element produces two peaks in its mass spectrum at

m/z=64

and

m/z=66

. The peak at 64 has twice the relative intensity of the peak at 66. Which of the following best describes the natural isotopic composition of the element? a) approximately 50\%

^{64}\text{X}

and 50\%

^{66}\text{X}

b) approximately 67\%

^{64}\text{X}

and 33\%

^{66}\text{X}

c) approximately 75\%

^{64}\text{X}

and 25\%

^{66}\text{X}

d) approximately 33\%

^{64}\text{X}

and 67\%

^{66}\text{X}
