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.

0.4(2x+1/2)=3[0.2x+(-2)]-4 solve the equation
melisa1 [442]
0.4(2x+1/2) = 3[0.2x-2]-4
0.8x+0.2 = 0.6x-6-4         Distribute it out
0.8x+0.2 = 0.6x-10          Combine like terms
0.2x = -10.2                     Subtract 0.6x and 0.2 from both sides
x = -51                             Multiply both sides by 5
