Question

1. if the average atomic mass of hydrogen in nature is 1.0079, what does that tell you about the percent composition of h - 1 and h - 2 in nature? # of h - 1 atoms # of h - 2 atoms % comp of h - 1 % comp of h - 2 average atomic mass

Explanation:

Step1: Calculate total number of atoms

$8 + 2=10$

Step2: Calculate % composition of H - 1

$\frac{8}{10}\times100 = 80\%$

Step3: Calculate % composition of H - 2

$\frac{2}{10}\times100 = 20\%$

Step4: Analyze the result

The average atomic mass of hydrogen is close to 1.0079. Since H - 1 has a mass of approximately 1 and H - 2 has a mass of approximately 2, the high percentage (80%) of H - 1 in nature pulls the average atomic mass close to 1.

Answer:

The high percentage (80%) of H - 1 in nature compared to H - 2 (20%) explains why the average atomic mass of hydrogen is close to the mass of H - 1.
