In water, the ratio of hydrogen atoms to oxygen atoms is 2 to 1. If there are 3×10 exponent 23 atoms is a sample of water, how many are hydrogen atoms
+259 2hydrogen atoms : 1 oxygen atom (h2o)
3*10^23 atoms II /3 because every 3rd atom is oxygen
means
1*10^23 atoms are oxygen
So the rest of
2*10^23 atoms are hydrogen.
Which means u got 10^23 H2 Atoms.
+36923 That would be 10^23 H2 MOLECULES (if they were in free molecular form...which they aren't)
