Let the 8% solution be A, the 20% solution be B and the final solution be C.
C = A + B
C = 12 + B
0.16C = 0.08(12) + 0.2(B)
0.16(12 + B) = 0.96 + 0.2B
0.96 = 0.04B
B = 24 Liters
C = 12 + 24
C = 36 Liters
Yep. And you'll always get equations with units that don't match
I think the answer is c. two molecules
Answer:
The distance between the centers of the two oxygen atoms in an oxygen molecule is 
Explanation:
We know, 1 inch = 2.54 cm
So, 
=
So the distance between the centers of the two oxygen atoms in an oxygen molecule is
Answer:
Table salt is 97% to 99% sodium chloride, NaCl. Pure sodium chloride is an ionic crystal solid. However, other compounds are present in table salt, depending on its source or additives that may be included before packaging. Hope this is helpful!
