Question

the average human body contains a total of 7×10^27 atoms. the table shows how many of those are hydrogen, nitrogen, radium, and gold atoms. how many more hydrogen atoms are there than nitrogen atoms in the human body? atoms in the human body type of atom hydrogen nitrogen radium gold number of atoms 4.22×10^27 3.9×10^25 8×10^10 2×10^19 there are more hydrogen a (type an integer or a decimal)

Explanation:

Step1: Identify the numbers

Hydrogen atoms: $4.22\times 10^{27}$, Nitrogen atoms: $3.9\times 10^{25}$

Step2: Make the exponents the same

Rewrite $3.9\times 10^{25}$ as $0.039\times 10^{27}$

Step3: Subtract

$(4.22 - 0.039)\times 10^{27}=4.181\times 10^{27}$

Answer:

$4.181\times 10^{27}$
