I didn't see an explanation in the movie. How many days pass on Earth when one SOL passes on Mars?
I heard a reference of two months passing, but I thought only (counts)....less than 50 SOLs had passed.

The physics of Mars in The Martian is identical to the actual physics of the planet, as such, we only need to know the actual length of a Martian sol (in hours/minutes) to know how it compares with an Earth day.
A Martian day is nearly identical to an Earth day. There's only a difference of about 2.7% between the two.
The average length of a Martian sidereal day is 24h 37m 22.663s (88,642.66300 seconds based on SI units), and the length of its solar day (often called a sol) is 24h 39m 35.244147s (88,775.244147 seconds). The corresponding values for Earth are 23h 56m 4.0916s and 24h 00m 00.002s, respectively. This yields a conversion factor of 1.02749125170 days/sol. Thus Mars' solar day is only about 2.7% longer than Earth's.
The number above you're interested in is the solar day - 24 hours, 39 minutes, 35 seconds.
