Answer:
7279
Step-by-step explanation:
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.
There’s are ratio which would be 8/10. 12/x should equally 8/10. So it would be 14 tiles long.
Answer: W= -0.75
Explanation: 8 x -0.75= -6
-6 + 9= 3
If f(x) = 6x , then f(2) = 6(2) or f(2) = 12... simply substitute the argument in for the variable in your expression on the right.
