There are 6.02214*10^23 molecules , I'm not so sure about it though.
The element neon, in period 2, has the most mass.
Hello there!
1. Synthesis: 2H₂ + O₂ → 2H₂O
2. Decomposition: 2HBr → H₂ + Br₂
3. Single-Replacement: 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
4. Double-Replacement: 2HCl + 2NaOH → 2H₂O + 2NaCl
5. Combustion: 2C₂H₆ + 7O₂ → 6H₂O + 4CO₂
I hope this helps!

Solve for x.
pv=xrt
Flip the equation.
rtx=pv
Divide both sides by rt.
rtx.rt = pv/rt
x = pv / rt
