question 6 (2 points) find the atomic mass of the following element symbol exact mass percent abundance 46x 45.952630 8.25 47x 46.951764 7.44 48x 47.947947 73.72 49x 48.947871 5.41 50x 49.944792 5.18 round your answer to exactly 6 decimal spots. the average mass listed on the periodic table will not get you credit! what is the element? blank 1: blank 2:

Answer

Explanation:

Step1: Convert percent abundances to decimals

$8.25% = 0.0825$, $7.44%=0.0744$, $73.72% = 0.7372$, $5.41%=0.0541$, $5.18% = 0.0518$

Step2: Calculate the contribution of each isotope

For $^{46}X$: $45.952630\times0.0825 = 3.791192$ For $^{47}X$: $46.951764\times0.0744 = 3.493212$ For $^{48}X$: $47.947947\times0.7372 = 35.358329$ For $^{49}X$: $48.947871\times0.0541 = 2.648080$ For $^{50}X$: $49.944792\times0.0518 = 2.586140$

Step3: Sum up the contributions

$3.791192+3.493212 + 35.358329+2.648080+2.586140=47.876953$

Answer:

$47.876953$
