Create a conversion factor from "<span>There are 6.02 × 10^23 atoms in 1 gram of hydrogen:"
6.02*10^23 atoms
-------------------------
1 gram
Then mult. 800 grams by this conversion factor:
</span>6.02*10^23 atoms 800 grams
------------------------- * ----------------
1 gram 1
This comes out to 4816*10^23 atoms, which, in scientific notation, is
4.816*10^26 atoms.

Answer:

will give you an explanation if you want tag me on comment.
Answer:
if ur simplifying its -24
−4(2+3)−4(5−4)
=(−4)(5)−4(5−4)
=−20−4(5−4)
=−20−(4)(1)
=−20−4
=−24
