Volume of 20 g of hydrogen at normal temperature and pressure (NTP) = 240.55 ml.

1mile/13min * 1min/60sec * 63360in/1mil = 63360in/780sec = 81.23 in/sec
Answer:
An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. ... Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals.

D=m/v ⇒v=m / d
d=density
m=mass
v=volume
d(Benzene)=0.88 g/cm³
m=20.0 g
v=m/d
v=20.0 g / (0.88 g/cm³)=22.73 cm³
Solution: v=22.73 cm³=22.73 ml
I would say the C, the windward side, sense it is wetter. Hope this helps. :)
