## Mackenzie2013 one year ago There are 6.02 × 1023 atoms in 1 gram of hydrogen. How many atoms are there in 800 grams of hydrogen? Write your answer in scientific notation. If necessary, round your answer to the nearest hundredth.

well 800 can be written as $8 \times 10^2$ so the problem is now $(6.02 \times 10^{23}) \times 800~~~~or~~~(6.02 \times 10^{23}) \times 8 \times 10^2 =$
