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.

Answer 1

That would be around 4.82 * 10^28

Answer 2

`6.02\cdot 10^(23)\cdot 800=4816\cdot 10^(23)\approx \boxed{4.82\cdot 10^(26)}`
