8. calculate the average atomic mass of the element hydrogen(h) using the following data: isotope % abundance hydrogen - 1 99% hydrogen - 2 0.8% hydrogen - 3 0.2%

8. calculate the average atomic mass of the element hydrogen(h) using the following data: isotope % abundance hydrogen - 1 99% hydrogen - 2 0.8% hydrogen - 3 0.2%

Answer

Explanation:

Step1: Convert percentages to decimals

$99% = 0.99$, $0.8%=0.008$, $0.2% = 0.002$

Step2: Multiply mass - abundance pairs

The mass of Hydrogen - 1 is approximately 1 amu, Hydrogen - 2 is approximately 2 amu, and Hydrogen - 3 is approximately 3 amu. For Hydrogen - 1: $1\times0.99 = 0.99$ For Hydrogen - 2: $2\times0.008=0.016$ For Hydrogen - 3: $3\times0.002 = 0.006$

Step3: Calculate average atomic mass

$0.99 + 0.016+0.006=1.012$ amu

Answer:

$1.012$ amu
